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? a. the number of moles of gas will decrease. b. the number of moles of gas will increase. c. the temperature of the gas will increase. d. the volume of the container will decrease. e. the volume of the container will increase.

D. The volume of the container will decrease.

Explanation:

PV = nRT,

where, P is the pressure of the gas.

V is the volume of the container.

n is the no. of moles of the gas.

R is the general gas constant.

T is the temperature of the gas.

Also, n is constant as there is no added external gases.

T is decreased as the container is cooled.

So, the volume will change as the container is nonrigid.

V α T.

The volume is directly proportional to the temperature,

Thus, as the container is cooled, the T will decrease, and the volume of the container will decrease.
