a mixture of he , n2 , and ar has a pressure of 13.6 bar . the partial pressure of he is 383 kpa and the partial pressure of ar is 401 kpa . calculate the partial pressure of n2 in bar.
Answers
A mixture of He, N2, and Ar has a pressure of 13.6 bar. The partial pressure of He is 383 kPa and the partial pressure of Ar is 401 kPa. The partial pressure of N2 would be 12.816 bar.
Calculating partial pressure of nitrogen:
To calculate the partial pressure of N2, we first need to find the total pressure contributed by He and Ar, and then subtract that from the total pressure of the mixture.
The partial pressure of He is given as 383 kPa, which is equal to 0.383 bar (since 1 bar = 100 kPa). Similarly, the partial pressure of Ar is given as 401 kPa, which is equal to 0.401 bar.
So the total pressure contributed by He and Ar is:
0.383 bar + 0.401 bar = 0.784 bar
Now, we can subtract this from the total pressure of the mixture to get the partial pressure of N2:
The total pressure of the mixture = 13.6 bar
The partial pressure of He = 0.383 bar
The partial pressure of Ar = 0.401 bar
The partial pressure of N2 = Total pressure of mixture - (Partial pressure of He + Partial pressure of Ar)
Partial pressure of N2 = 13.6 bar - (0.383 bar + 0.401 bar)
Partial pressure of N2 = 12.816 bar
Therefore, the partial pressure of N2 in the mixture is 12.816 bar.

Newton's heating-cooling law states that the rate of change in the temperature, H, is proportional to the difference between the object and the surrounding temperature. Let H(t) be the temperature of the object being cooled and S be the surrounding temperature. A warm object at 100 degrees is placed in a refrigerator at 35 degrees Fahrenheit and after 30 minutes the object is 75 degrees. Write and solve the differential equation which describes the temperature of the object over time, where time is measured in hours. OH(t)=35-65e-0.97t OH(t)=35+65e-t(0.97) OH(t)=75-35e-0.97t OH(t)=35+75e0.971
Answers
The differential equation which describes the temperature of the object over time is;
dH/dt = -k (H-S), where k = 0.97. The solution to this differential equation is given by H(t) = S + 65e^(-0.97t).
Newton’s law of heating and cooling is an application of the first law of thermodynamics. The law suggests that the rate of change of temperature of an object is proportional to the difference between its temperature and the temperature of the surroundings.
A warm object is placed in a refrigerator where the surrounding temperature is cooler, and the temperature of the object decreases. This phenomenon can be explained using differential equations. Given that H(t) is the temperature of the object being cooled and S is the surrounding temperature, the differential equation which describes the temperature of the object over time is given by;dH/dt = -k (H-S)
where k is the constant of proportionality.To solve this differential equation, we can use separation of variables, such that;
dH/dt = -k (H-S)dH/(H-S) = -k dt
Integrating both sides, we get;ln|H-S| = -kt + Cwhere C is the constant of integration.Rearranging, we have;
|H-S| = e^(-kt+C)
At time, t = 0, H = 100 and after 30 minutes the object is 75 degrees; t = 0.5 hours, H = 75. We can use these values to solve for C and k as follows;
|100-35| = e^(C) => 65 = e^(C) …(1)
and|75-35| = e^(-0.5k+C) => 40 = e^(C) e^(-0.5k) => e^(-0.5k) = 40/65 => e^(-0.5k) = 8/13 => -0.5k = ln(8/13) => k = -2ln(8/13) => k = 0.97 …(2)
Substituting equation (1) into (2), we get;H-S = 65e^(-0.97t) => H(t) = S + 65e^(-0.97t)
Therefore, the differential equation which describes the temperature of the object over time is;dH/dt = -k (H-S), where k = 0.97.
The solution to this differential equation is given by H(t) = S + 65e^(-0.97t).

Two positively charged particles repel each other with a force of magnitude Fold. If the charges of both particles are doubled and the distance separating them is also doubled, what is the ratio of the new force compared to the original force, Fox? , Flex Fold
Answers
The ratio of the new force compared to the original force is `1`.
Given that two positively charged particles repel each other with a force of magnitude `Fold`.
The charges of both particles are doubled and the distance separating them is also doubled.
To find: What is the ratio of the new force compared to the original force,
We know that the force between two charged particles is given by Coulomb's law as,
F = k(q₁q₂)/r²where,
k = Coulomb constant = 9 × 10⁹ Nm²/C²
q₁ = charge of particle 1
q₂ = charge of particle 2
r = distance between two charged particles.
Now, According to the question,Q₁ and Q₂ charges of both particles have doubled, then
new charges are = 2q₁ and 2q₂
Also, the distance separating them is also doubled, then
new distance is = 2r.
Putting these values in Coulomb's law, the
new force (F') between them is,
F' = k(2q₁ × 2q₂)/(2r)²
F' = k(4q₁q₂)/(4r²)
F' = (kq₁q₂)/(r²) = Fold
The ratio of the new force compared to the original force is given by;
Fox = F'/Fold= 1
Therefore, the ratio of the new force compared to the original force is `1`.

why don't the air molecules in your room all spontaneously collect in one half of the room, leaving the other half of the room completely empty of air? newtons law
Answers
The answer is entropy here. It's quite unlikely that spontaneously air molecules moves exclusively to one half of your room. This can be explained by understanding the concept of entropy and second law of thermodynamics.
Why is the second law of thermodynamics true?Entropy is the measure of disturbance or disorder of universe.
The second law of thermodynamics states that entropy of an isolated system doesn't decrease over time.
The second law of thermodynamics is true because there are very few ways that particles can be concentrated in an area. In most situations, the particles are evenly distributed. Similarly, in a room, the particles are evenly distributed and as particles start moving, there is a nonzero probability of low entropy state, Most of the time the system will increase in entropy that is increase in disturbance evenly. Hence it is not possible that air molecules will collect in one part of the room and not on the other part.

A proton is confined to moving in a one-dimensional box of width 0.200 nm.
(a) Find the lowest possible energy of the proton.
(b) What is the lowest possible energy of an electron confined to the same box?
(c) How do you account for the large difference in your results for (a) and (b)?
Answers
The question discusses a proton and an electron confined to a one-dimensional box with a width of 0.200 nm. It asks for the lowest possible energy of the proton.
(a) The lowest possible energy of a proton confined to a one-dimensional box can be found using the equation E = (n^2 * h^2) / (8 * m * L^2), where E is the energy, n is the quantum number (1 for the ground state), h is the Planck's constant, m is the mass of the proton, and L is the width of the box.
Substituting the values, we have E = (1^2 * h^2) / (8 * m * L^2). Calculating this expression will give us the lowest possible energy of the proton in the given one-dimensional box.
(b) For an electron confined to the same one-dimensional box, the lowest possible energy can be calculated using the same equation as in part (a). However, the mass of the electron and its quantum number will be used in the calculation.
(c) The large difference in the results for parts (a) and (b) can be attributed to the significant difference in mass between a proton and an electron. The mass of a proton is approximately 1836 times greater than that of an electron. This difference in mass affects the energy levels and results in the proton having a much higher energy compared to the electron in the same size box.

If a transformer doubles its input voltage, what is the current in the secondary coil if the primary coil is 10 A.
Answers
Answer:
20Amp
Explanation:
Using the transformer formula
Vs/Vp = Ns/Np = Ip/Is
Vs/Vp = Ip/Is
Vp is the primary voltage = input voltage
Vs is the secondary voltage = output voltage
Ip is the current in the primary coil
Is is the amount of current in the secondary coil.
If the transformer doubles its input voltage Vp, its output voltage Vs will be
decreased by 2 but the output current will be doubled
Given the input current Ip = 10A, the current in the secondary coil (output current) will be doubled i.e Is = 2(10) = 20A
The current in the secondary coil be "50 A". To understand the calculation, check below.
Current and VoltageAccording to the question,
Current in primary coil, \(I_{in}\) = 10 A
We know the relation,
Power = \(V_{in} I_{in}\) = \(V_{out} I_{out}\)
then,
→ \(V_{in} I_{in}\) = \(V_{out} I_{out}\)
By substituting the values,
\(V_{in}\) × 10 = 2 \(V_{in} I_{out}\)
By applying cross-multiplication,
10 = 2 \(I_{out}\)
\(I_{out}\) = \(\frac{10}{2}\)
= 5 A
Thus the response above is correct.

Explain why precipitation on earths surface is less common on land than itbis over the oceons. Base your answer on the water cycle
Answers
The combination of the vast moisture availability and relatively stable atmospheric conditions over the oceans contributes to more frequent precipitation compared to land areas.Due to this precipitation on earths surface is less common.
Precipitation on Earth's surface is generally less common on land compared to over the oceans due to several factors related to the water cycle. The water cycle involves the continuous movement of water between the atmosphere, land, and oceans.
Firstly, the oceans cover a significant portion of the Earth's surface, which means there is a larger expanse of water available for evaporation. Evaporation occurs when water from the surface of oceans turns into water vapor, rising into the atmosphere. The vastness of the oceans provides ample moisture for evaporation, resulting in a greater supply of water vapor in the atmosphere.
Secondly, land surfaces tend to heat up and cool down more quickly than the oceans. This difference in temperature leads to variations in air pressure and creates atmospheric circulation patterns. As warm air rises over land areas, it expands and cools, causing water vapor to condense and form clouds. However, the land areas often lack the necessary moisture content to sustain significant cloud formation and subsequent precipitation.
Moreover, when moist air masses from the oceans encounter land masses, they are forced to rise due to the topography of the land. As the air rises, it cools, leading to condensation and cloud formation. However, the presence of mountains or other geographical features can enhance this lifting process, resulting in increased precipitation in certain regions.
Overall, the combination of the vast moisture availability and relatively stable atmospheric conditions over the oceans contributes to more frequent precipitation compared to land areas. Land surfaces, with their varying temperatures, limited moisture content, and topographical features, often experience less common and more localized precipitation events.

Two 50 g metal blocks, one made of lead and the other of iron, are heated to 100°C. They are placed in identical calorimeters, each with 100 g of water at a starting temperature of 20°C. Which calorimeter will have the higher temperature at thermal equilibrium: the one with lead or the one with iron? Explain your answer
Answers
calorimeter with iron will have the higher temperature at thermal equilibrium.
The particular heat capacity (symbol c) of a material in thermodynamics is the heat capacity of a sample of the substance divided by the mass of the sample, also known as massic heat capacity. Informally, it is the quantity of heat that must be added to one unit of mass of the substance to generate one unit of temperature increase. Specific heat capacity is measured in joules per kelvin per kilogramme, or J⋅kg−1⋅K−1, The heat required to increase the temperature of 1 kilogramme of water by 1 K, for example, is 4184 joules, hence the specific heat capacity of water is 4184 J⋅kg−1⋅K−1. calorimeter with high specific heat have the higher temperature at thermal equilibrium.
In this problem, specific heat of lead is 120 J/kg.°C. and that of iron is 450 J/kg°C.
if the both elements are heated from room temperature 25°C to 100°C,
Total heat contained in lead is,
Q = cmΔT = 120×0.05kg×75°C = 450 J
Total heat contained in iron is,
Q = cmΔT = 450×0.05kg×75°C = 1687 J
Specific heat of the water is 4.2 J/g°C.
Temperature of the calorimeter due to lead
T₂ - T₁ = Q/cm = 450/4.2×100
T₂ - 25 = 1.07
T₂ = 1.07 +25 = 26.07°C
Temperature of the calorimeter due to iron
T₂ - T₁ = Q/cm = 1687 /4.2×100
T₂ - 25 = 4.01
