Question

According to kinetic molecular theory, the average kinetic energy does not change as long as the _____ remains constant.

A) Pressure
B) Temperature
C) Volume
D) Density

Answer 1

The average kinetic energy of a system's molecules remains unchanged as long as the temperature remains constant, according to kinetic molecular theory.

Step-by-step explanation:

According to kinetic molecular theory, the average kinetic energy does not change as long as the temperature remains constant. This is because the temperature of a system is a measure of the average kinetic energy of its molecules. At a constant temperature, even if the pressure, volume, or density of the system changes, the average kinetic energy per molecule remains unchanged, in accordance with the equation K = kBT, where K is the average kinetic energy, KB is the Boltzmann constant, and T is the temperature.
