question 9
which statement about thermal energy is true?
its the same as the substances temperature
its a measure of the movement of a substances molecules
its a measure of a substances specific heat

Explanation:

Thermal energy is the total kinetic energy of all the molecules in a substance, meaning it measures the movement of a substance's molecules. Temperature is the average kinetic energy of molecules (not the same as total thermal energy), and specific heat is a property related to how much energy is needed to change a substance's temperature, not thermal energy itself.

Answer:

it's a measure of the movement of a substance's molecules
