Heat-
Heat- refers to thermal energy, a form of energy arising from the random motion of atoms and molecules within a substance. It is the transfer of this energy from a warmer object or system to a cooler one. Heat is measured in units like Joules or calories and profoundly influences the state, temperature, and physical properties of matter. The term often implies elevated temperature, warmth, or a condition of high energy content. It can also be associated with the sensation of warmth or a process involving the application or generation of thermal energy. Heat can be beneficial (e.g., heating a home) or detrimental (e.g., causing burns).
