What is the relationship between the kinetic energy of molecules in an object and the object's temperature?

Natalija [7]

Answer: as the temperature increases, the kinetic energy of the molecules increases

Explanation: The kinetic energy of the molecules is the energy possessed by virtue of motion of the particles.

Kinetic energy of the particles is directly proportional to the temperature of the gas.

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

where T= temperature

R= gas constant

Thus if the temperature is increased, the molecules start moving more randomly and gain kinetic energy.
