How does an increase in thermal energy affect molecules?

a) they stop moving.
b) they begin to vibrate more.
c) they decrease in temperature.
d) they lose kinetic energy.

The answer is B. They begin to vibrate more.

The answer is B. They begin to vibrate more.

Answer;

b) They begin to vibrate more.

Explanation;Thermal energy or heat energy is energy that results from heating or increasing the temperature of a substances.When substances are heated their molecules and atoms gain more kinetic energy and therefore they begin to vibrate more, as they bombard and collide faster with each other.Therefore, when thermal energy or heat is increased the atoms and molecules within a substance move faster thus increasing their kinetic energy.
