An increase in the number of gas molecules in the same volume container increases pressure. This means the gas pressure inside the container will increase (for an instant), becoming greater than the pressure on the outside of the walls. With a smaller volume, the gas molecules will hit the walls more frequently, and so the pressure increases. Gas B has a molar mass that is twice that of gas A. Explain your answer.
