Helium gas is being pumped into a rigid container at a constant temperature. As a result, the pressure of helium in the container is increasing. Select the one correct statement below.
A)As the pressure increases, helium atoms move faster, on average.
B)As the pressure increases, helium atoms move more slowly, on average.
C)As the pressure increases, the volume of the container must decrease.
D)As the pressure increases, helium atoms stay closer to the wall of the container, on average.
E)As the pressure increases, there are more collisions of helium atoms with the container wall.

Question

Quizplus · Accepted Answer

As the pressure of helium in the container increases, the number of collisions of helium atoms with the container wall also increases. This is because the gas molecules are colliding with each other more frequently, which in turn increases the number of collisions with the container walls. The other options are incorrect as they do not accurately describe the behavior of gas molecules under increasing pressure.
