A sample of gas has a pressure due to the collisions of moving gas particles with the container walls. This pressure can be understood at the particle level. Each collision of a gas particle with the container wall results in a force on the wall. Because there are so many particles colliding so frequently with the container wall, there is enough force that accumulates to result in a noticeable pressure. Any variable that effects the ratio of the cumulative amount of force per unit of wall area will effect this pressure.

Version 1:
Which set of variables when taken together will result in the highest pressure?
High number of small particles moving fast in a small container.
Low number of small particles moving slowly in a large container.
Low number of small particles moving slowly in a small container.
High number of massive particles moving fast in a large container.
Low number of massive particles moving slowly in a large container.
High number of massive particles moving very fast in a small container.
