Two gases have the same temperature but different pressures. The kinetic-molecular theory does not predict that a. molecules in
olganol [36]

Answer: Option (c) is the correct answer.

Explanation:

Kinetic molecular theory states that particles of a matter are continuously in motion and these molecules represent perfect elastic collision.

So, at the same temperature but different pressures the two gases will have all collisions of the molecules as elastic in nature. It is also possible that molecules in both gases have the same average kinetic energies under given conditions as their molecules might be moving with the same speed.

But we cannot determine the densities of these gases.

Thus, we can conclude that the kinetic-molecular theory does not predict that both gases have the same densities.

A gas at constant volume has a pressure of 4. 50 atm at 200. K. What will be the pressure of the gas at 250. K? 3. 60 atm 4. 60
Trava [24]

5.625 atm will be the pressure of the gas at 250 K temperature of the gas at constant volume.

<h3>How we calculate the pressure of the gas?</h3>

Pressure of the gas will be calculated by using the ideal gas equation as:

PV = nRT,

From the question, it is clear that:

Moles of the gas and volume is constant here, so we calculate the pressure by rearranging the above equation as:

P/T = nR/V

And required equation will be:

P₁/T₁ = P₂/T₂, where

P₁ = pressure of gas = 4.50 atm

T₁ = temperature of gas = 200 K

P₂ = pressure of gas = to find?

T₂ = temperature of gas = 250 K

On putting all these values in the above equation, we get

P₂ = 4.50 × 250 / 200 = 5.625 atm

Hence, 5.625 atm is the pressure of the gas.
