Mini-Quiz: Thermal Potential Energy

1. What happens to the thermal potential energy when a piece of paper burns?

   The paper becomes complete thermal potential energyGood try, but not right. Select another answer. The potential energy is released as kinetic energy and increased temperatureThat is correct. You know your thermal energy. The thermal potential energy become neutralizedSorry, not correct. Try another button.

2. What happens when molecular electrostatic forces are released?

   The material can change its state or phaseCorrect. You understand the subject! The molecules stick togetherOops! Wrong answer. Re-read the question and try again. Potential energy is increasedSorry, not correct. Try another button.

3. How can nuclear decay increase the thermal kinetic energy of a material?

   High energy nuclear particles collide with molecules to increase their kinetic energyThat is correct. You know your thermal energy. Decay changes the environment of the material, thus heating it upGood try, but not right. Select another answer. Nuclear decay gives off hot particles that can cause damage to the materialSorry, not correct. Try another button.
