What three factors affect the pressure of a gas in a closed container?

Number of moles of the gas, Temperature and the volume of the gas.

The three factors that affect gas pressure are the number of gas molecules, the volume of the container and the temperature of the container that contains the gas. If there are two equal-sized containers, and one contains double the amount of gas molecules, this container has a higher gas pressure.
