Question

particles together can exert more force.
the diagrams below show two pure samples of gas in identical closed, rigid containers.
gas a and gas b have the same temperature.
look at the number of particles in each gas. which has the higher gas pressure?
gas a
gas b
neither; their gas pressures are the same

Explanation:

Pressure of a gas in a closed, rigid container is related to the number of gas particles. More particles mean more frequent collisions with the container walls, resulting in higher pressure. Here, gas B has more particles than gas A.

Answer:

gas B
