Heat is the flow of energy from one object to another. This flow of energy is caused by a difference in temperature. The transfer of heat can change temperature, as can work, another kind of energy transfer that is central to thermodynamics.
A natural light source refers to a light source that is able to give off light naturally. For example, the Sun , which lights up the Earth during the day, is a natural source of light. The stars that we see in our night sky, together with fireflies and lightning , are other examples of natural light sources.
6 mar 2024 · Heat Definition. Heat is the thermal energy transfer between systems or bodies due to a temperature difference. Thermal energy, in turn, is the kinetic energy of vibrating and colliding particles. Heat occurs spontaneously from a hotter body to a colder one.
