Quizplus · Accepted Answer

The average kinetic energy of an ideal gas is directly proportional to its temperature. If the kinetic energy increases, the temperature must also increase. According to the ideal gas law (PV=nRT), if the temperature (T) increases while the volume (V) is fixed and the amount of gas (n) remains constant, both the pressure (P) and temperature must increase.
