select the correct answer. a certain 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.

Question

Accepted Answer

# Answer:
D. The volume of the container will decrease.
# Explanation:
## Step1: Recall Charles's Law
Charles's Law states that $V_1/T_1 = V_2/T_2$ (at constant pressure and amount of gas), where $V$ is volume and $T$ is temperature in Kelvin.
## Step2: Analyze the cooling situation
The container is cooled, so $T_2<T_1$. Since pressure is constant and amount of gas is constant (trapped gas), from $V_1/T_1 = V_2/T_2$, we can rewrite it as $V_2=\frac{T_2}{T_1}V_1$. As $T_2<T_1$, $\frac{T_2}{T_1}< 1$, so $V_2 < V_1$. Thus the volume of the container will decrease.
