Question

Question 28 of 25 What is thermal energy? A. The average kinetic energy of molecules in a system B. The difference in potential energy between two states C. The total kinetic energy of the particles in a system D. The transfer of chemical energy between molecules

Answer 1

The correct answer is 'C'.

Answer 2

## Step 1Thermal energy is a form of energy that is associated with the temperature of an object. the total kinetic energy of the particles in a system. ## Step 2The kinetic energy of particles is due to their motion. The faster the particles move, the higher the thermal energy of the system. ## Step 3Option A refers to the average kinetic energy of molecules in a system, which is actually the definition of temperature, not thermal energy. ## Step 4Option B describes the difference in potential energy between two states, which is not related to thermal energy. ## Step 5Option D describes the transfer of chemical energy between molecules, which is a chemical reaction and not thermal energy.
