Q10 of 100 Page 32

A gas is kept in an enclosure. The pressure of the gas is reduced by pumping out some gas. Will the temperature of the gas decrease by Charles’s law?

No, temperature will not decrease.

Explanation


Charles’s law states that for fixed pressure, volume of a gas is proportional to its absolute temperature.


VT …… (pressure=constant)


So, Charles’s law is not even applicable because the pressure of the gas is being reduced in question.

If it were possible for a gas in a container to reach the temperature 0 K, its pressure would be zero. Would the molecules not collide with the walls? Would they not transfer momentum to the walls?

 9

It is said that the assumptions of kinetic theory are good for gases having low densities. Suppose a container is so evacuated

that only one molecule is left in it. Which of the assumptions of kinetic theory will not be valid for such a situation? Can we assign a temperature to this gas?

Explain why cooking is faster in a pressure cooker.

If the molecules were not allowed to collide among themselves, would you expect more evaporation or less evaporation?
