Pressure and Temperature

Postby Dhwani Krishnan 1G » Sun Jan 13, 2019 6:11 pm

According to the Ideal Gas Law, P = nRT/V. Therefore, P and T are directly proportional. My question is, conceptually, how/why does an increase in Pressure cause and increase in Temperature and vice-versa?

Temperature is directly proportional to the average kinetic energy of molecules of a gas. By increasing the pressure these molecules are placed in a more compact setting, causing them to bounce off each other more frequently, and thus move faster. As these molecules move faster, the temperature increases.
Conversely, as you increase the temperature, these molecules move faster in a confined space, thereby increasing the pressure of the gas.

As temperature increases, the molecules of gas have more energy and begin striking the walls of a container with higher frequency. Essentially, the molecules exhibit a higher pressure on the container since they attempt to further themselves from each other.
