Consider a sealed glass bottle of helium gas at room temperature. If you immerse the bottle in an ice water bath, how will this immersion affect the pressure of the gas?

I. Pressure increase

II. Pressure decrease

III. No pressure change

The best explanation for your answer is?

a The force of the collisions of the helium atoms with the container walls increases with decreasing temperature.

b The helium atoms have significantly greater volumes at lower temperatures. 

c The frequency and force of the collisions of the helium atoms with the container walls decrease with decreasing temperature.

d The average kinetic energy of the helium atoms remains constant when the temperature decreases.

e The concentration of helium decreases, resulting in a decrease in the frequency of the collisions with the container walls.
