What is heat?

Heat is the change of temperature. It is sensitive to both hot and cold. Heat is made up of atoms, molecules and energy. We can measure heat in three ways, conduction, convection, and radiation. Conduction is the process or action of heat or electricity that is directly transferred through a substance. The material is directly affected by the change of temperature. The process of heat or electricity, is passed through a substance. Convection is the movement caused within a liquid that likely transferred and spread heat. It is the rapid motion of heat causing less dense material to rise and the colder material to sink down. Radiation is the release of the electromagnetic waves as energy, which causes ionization of molecules to positive and negative atom bonding. By: Estelle
