6.1: Heat Flow - Chemistry LibreTexts

Figure 5.5.1: Combustion of gasoline produces energy which moves the car and generates heat. Heat is energy that is transferred from one object or substance to another because of a difference in temperature between them. Heat always flows from an object at a higher temperature to an object at a lower temperature (see figure below).

1. Kinetic Energy, Heat Energy and Temperature |

Heat Energy. The total kinetic energy of all particles in a substance is referred to as heat energy or thermal energy. Heat energy can be measured in joules (J) or calories (cal). Heat energy is related to the amount (mass) of a substance. For example, 2 kg of iron has twice as much heat energy as 1 kg of iron at the same temperature.
