When a gas is forced into a smaller volume without a change in temperature, its pressure increases because its molecules
A) strike the container walls more often.
B) strike the container walls at higher speeds.
C) strike the container walls with greater force.
D) have more energy.

Question

Quizplus · Accepted Answer

When a gas is compressed into a smaller volume without a change in temperature, its molecules strike the container walls more often due to the reduced space, leading to an increase in pressure. The speed, force of each collision, and energy of the molecules remain constant if the temperature is unchanged.
