Question

Quizplus · Accepted Answer

Heat is a form of energy that is transferred between two objects or systems as a result of a temperature difference. Temperature (A) is a measure of the average kinetic energy of the particles in a substance, and how hot something is (B) is a subjective description of temperature. The difference in temperature between two objects (C) is important in determining the direction of heat flow, but it is not the ultimate definition of heat. Whether something rises or sinks (E) is related to density and buoyancy, not specifically to heat.
