Question

A chemist cools (decreases the temperature) a gas within a sealed, rigid container. Which statement describes the changes that occur in the gas? The volume of the container is constant.





a
The gas particles move slower and hit the sides of the container with less force, consequently, the pressure increases.
b
The gas particles move slower and hit the sides of the container with less force, consequently, the pressure decreases.
c
The gas particles move faster and hit the sides of the container with more force, consequently, the pressure increases.
d
The gas particles move faster and hit the sides of the container with more force, consequently, the pressure decreases.

Answer 1

b) The gas particles move slower and hit the sides of the container with less force, consequently, the pressure decreases.
