Question

The average kinetic energy of the particles in an object is directly proportional to its
a. heat.
b. volume.
c. temperature.
d. potential energy.

Answer 1

C. Temperature the average  kinetic energy of the particles in an object is directly proportional to its temperature 

Answer 2

Answer: c) temperature

Explanation:

Kinetic energy is the energy possessed by an object by virtue of its motion.

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

$K=\frac{3RT}{2}$

From above, it is visible that kinetic energy is directly related to the temperature of the system. So, if temperature is more, average kinetic energy of the system is more and vice-versa.
