Heat
Definition
Heat refers to the transfer of energy between objects or systems due to a temperature difference. It can be measured in joules (J) or kilojoules (kJ).
Analogy
Think of heat as the energy that flows from a hot object to a cold object, just like how warmth spreads from a cup of hot cocoa to your hands on a chilly day.
