According to the kinetic-molecular theory, the average kinetic energy of gas particles depends on temperature. The correct option is C.
What is the kinetic-molecular theory?
The kinetic molecular theory is the assumption that matter is made up of microscopic particles that are always in motion, which explains the states of matter. The observable characteristics and behaviors of solids, liquids, and gases are explained by this theory.
The average kinetic energy of a particle of gas would be depending on the temperature because as the temperature increase the particle moves fast. So if the temperature increases the kinetic energy will increase and if the temperature decreases the kinetic energy of the particles would decrease.
Thus, the correct option is C: Temperature.
