Explanation: just took the quiz

Answer 2

Thermal energy is THE MEASURE OF TEMPERATURE IN A SYSTEM.
Thermal energy refers to the internal energy that is present in a system as a result of its temperature. The motion of the particles of an object depends on the temperature of the object and the higher the temperature, the faster the movement of the particles. The reverse is also true.
