Answer to Question 1

Answer: A

Answer to Question 2

Answer: Thermal energy, measured in calories or joules, is the energy something has by virtue of the molecular motion of its molecules. The more molecular kinetic energy, the more thermal energy. Temperature relates to the translational part of this kinetic energy per molecule in a substance, measured in degrees (or kelvins). Heat is thermal energy in transit; the thermal energy that transfers from one place to another by virtue of a temperature difference. Heat, like thermal energy, is measured in calories or joules.
