Does Reducing Pressure Reduce Temperature?

In a direct relationship, one variable follows the same change when it comes to increasing and decreasing. For example, when the pressure increases then the temperature also increases. When the pressure decreases, then the temperature decreases.

What happens to temperature If you decrease the pressure?

Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase. However, if you were to maintain a constant volume while decreasing pressure, the temperature would also have to decrease.

Does pressure decrease as temperature increases?

As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also increase.
