Heat - Physics for Aviation

Heat is a form of energy. It is produced only by the conversion of one of the other forms of energy. Heat may also be defined as the total kinetic energy of the molecules of any substance.

Some forms of energy which can be converted into heat energy are as follows:
  • Mechanical Energy—this includes all methods of producing increased motion of molecules such as friction, impact of bodies, or compression of gases.
  • Electrical Energy—electrical energy is converted to heat energy when an electric current flows through any form of resistance such as an electric iron, electric light, or an electric blanket.
