Which statement best describes the difference between heat and temperature?

• A. Temperature is a measure of how hot or cold something is; heat is energy transferred due to a temperature difference.
• B. Heat measures how hot something is, while temperature measures energy
• C. Temperature is energy transferred when particles move; heat is how warm something feels
• D. Heat and Temperature are the same thing

Answer: (A)

The main idea here is that temperature and heat describe two different things in how thermal energy moves. Temperature is a measure of how hot or cold something is—it's a property of the object, and we read it with a thermometer. Heat, on the other hand, is energy in transit that moves from a warmer object to a cooler one because there’s a temperature difference.

That’s why this statement is the best description: temperature tells us how hot or cold something is, while heat is the energy that flows because of a temperature difference. For example, if you touch a hot cup, energy is flowing from the cup to your hand as heat, and the cup’s temperature is high because it contains a lot of that energy.

The other ideas mix up these definitions. Heat is not a measure of how hot something is; it’s about energy moving between objects. Temperature is not energy transferred when particles move; it’s a measure of how hot or cold the object’s particles are on average. And heat and temperature are not the same thing.
