How is the temperature of a substance is related to kinetic energy of its molecules

The more kinetic energy, the higher the temperature.

Explanation:

Here is the guidelines on that assignment on EDG:

Every substance is composed of molecules that have kinetic energy.

Temperature is a measure of the average kinetic energy of molecules in the substance.

Temperature is measured in units of degrees.

As the kinetic energy of molecules increases, temperature also increases, and vice versa.

The more kinetic energy of its molecules, the higher temperature.

Explanation:

More kinetic energy means that the molecules are moving around more and bumping into each other more. This is correlated with a higher temperature as temperature is a measure of kinetic energy.
