👉 Heat is a form of energy that occurs when matter changes from a solid, liquid or gas to a state of high temperature. Heat can be transferred through conduction, radiation, and convection. In the context of physics and chemistry, heat is often used to describe the transfer of thermal energy in an object or system. It is also used in engineering applications such as heating systems, cooling systems, and appliances. Heat is a fundamental concept that plays a crucial role in many processes within the natural world
