A Child's Ideas about Heat Concept Physics Assignment
4 pages (2744 words) , Download 0 , Assignment
Free
Heat is a form of energy, specifically, the energy movement from two entities that have different temperatures. Since all objects have thermal energy, heat can also be defined as the transference of thermal energy from an object to its surroundings or to other objects. There are three ways that thermal energy (heat) can be transferred: Conduction, Convection, Radiation.
