Which step will decrease the pressure of a gas inside a closed cubical container? increasing the number of moles of gas decreasing the volume of the container increasing the speed of the gas particles decreasing the temperature inside the container

This item is asking us to determine the step that is most likely to decrease the pressure of the gas inside a closed cubical container. Among the given choices, the answer is decreasing of temperature. This is because the temperature and pressure are directly proportional. The decrease in pressure will cause decreasing in temperature.
