Temperature is the measure of coldness or hotness shown in terms of any measuring scale. It indicates the trajectory in which heat energy spontaneously propagates. Heat flows from a hotter body (higher temperature) to a colder body (lower temperature). Temperature is not similar to thermodynamic system energy. For example, burning wood possesses a much higher temperature than an ice glacier. However, the total heat energy accumulated in a block of wood is much lesser than the energy contained in an ice glacier. Just like density or pressure, the temperature is also called an intensive property (independent of the given matter quantity).
Temperature is a physical entity that expresses cold and hot. It is the result of thermal energy existing in all matter. Thermal energy is the source of the phenomenon of heat. Heat is the flow of energy when an object is in contact with another that is hotter or colder. Temperature is not the same as heat.
