Acertain amount of gas is trapped in a nonrigid container at atmospheric pressure. if the container is cooled and the gas in the container
remains at atmospheric pressure, what will happen?
o a.
the number of moles of gas will decrease.
ob. the number of moles of gas will increase.
oc. the temperature of the gas will increase.
od.
the volume of the container will decrease.
o e.
the volume of the container will increase.

Explanation:

Given that the gas is trapped,so the gas cant escape.

The number of moles of gas inside the container will remain constant.

The initial and final pressures are the same.

So,pressure can be taken as constant.

Charles law states that at constant temperature,volume of a system is directly proportional to the temperature of the system.

Since the temperature is lowered,volume also decreases.

the answer would be b i believe
