Factors Affecting Gas Pressure

Amount of Gas

Volume
“Weight is additionally influenced by the volume of the holder. On the off chance that the volume of a compartment is diminished, the gas atoms have less space in which to move around. As a result, they will strike the walls of the container more often and the pressure increases.

Temperature
“It would be extremely unadvisable to put a jar of soup over a pit fire without venting the can. As the can warms up, it might detonate.” The kinetic-molecular theory explains why. The air inside the rigid can of soup is given more kinetic energy by the heat coming from the campfire.

Summary
An increase in the number of gas molecules in the same volume container increases pressure.
A decrease in container volume increases gas pressure.
An increase in temperature of a gas in a rigid container increases the pressure.
