It occurs from the sun or electricity or fire. Or from the release of heat.
Heat energy is always released during an exothermic process. This means that the system loses heat to its surroundings as the process occurs.
Heat is always transferred from areas of higher temperature to areas of lower temperature. This transfer occurs through conduction, convection, or radiation.
Heat transfer occurs from hot to cold. Heat always moves from a higher temperature to a lower temperature.
Heat always moves from a warmer object to a cooler object. Heat transfer occurs until both objects reach the same temperature, establishing thermal equilibrium.
Heat always moves from an area of higher temperature to an area of lower temperature. This transfer occurs until both areas reach thermal equilibrium.
Heat energy always moves from warmer objects to colder objects, following the principle of the second law of thermodynamics. This transfer of heat occurs until thermal equilibrium is reached between the objects.
Heat does not always attract more heat. In fact, heat will always be attracted by something that contains allot less heat than the original amount of heat.
Heat energy always moves from a warmer object to a cooler object due to the process of heat transfer called conduction. This transfer occurs until thermal equilibrium is reached and both objects have the same temperature.
Boiling occurs when heat is supplied. Water is converted into vapor.
it combusts
Yes. (That's why refrigerators are a kind of a trick - an inefficient one.)
less friction occurs and heat is reduced
