Question

The pressure inside a container of gas increases if more gas is added to the container because

A. there is an increase in the number of particles striking an area of the wall of the container per unit of time.
B. there is an increase in the temperature.
C. there is a decrease in volume.
D. there is an increase in the force of each collision between a particle and the walls of the container.

Answer 1

Option A.

Once more gas is put inside a container, that means more molecules will be inside the container. Because of this, there will be a higher number of molecules hitting the sides of the walls, meaning that the pressure will be increased.
