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

The total kinetic energy of the molecules is not affected by a change in temperature.

The kinetic energy always increases whether the temperature increases or decreases.

As the kinetic energy of the molecules decreases, the temperature increases.

As the temperature increases, the kinetic energy of the molecules increases.

Jadon Hutchinson · Answer 1

Correct answer:

As the temperature increases, the kinetic energy of the molecules increases.

Explanation:

The relation between kinetic energy and temperature in an ideal gas which we will take as an example is given by the following formula:

Ek = 3/2 N k T,

where N is the total number of molecules a k is a Boltzmann constant.

If we assume that the total number of molecules is a constant, kinetic energy only depends on temperature.
