The of a material is a measure of the average kinetic (motion) energy of the molecules in the material. As the increases, a solid turns into a gas when the particles are moving fast enough to break free of the chemical bonds that held them together. (both blanks are the same answer)

Explanation:

The measure of average kinetic energy of particles or molecules of a substance is known as temperature.

When we increase the temperature of a substance then its molecules tend to gain kinetic energy because of which these molecules collide with each other. Hence, they move away from each other leading to change in the state of matter.

This means that increase in temperature changes solid into liquid and liquid into gas.

Thus, we can conclude that the temperature of a material is a measure of the average kinetic (motion) energy of the molecules in the material. As the temperature increases, a solid turns into a gas when the particles are moving fast enough to break free of the chemical bonds that held them together.
