Question

where does heat come from?​

Answer 1

Answer:

Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat

Answer 2

Heat comes from something hotter, and is the energy of the atoms vibrating. Most of the Earth's heat comes by radiation from the Sun. Most of the rest used by man comes from combustion of fossil fuels (oils and natural gas), hydro (from Sun-related weather), and nuclear sources
