Heat is the motion of atoms and molecules that is transferred to other atoms and molecules.  It is the measurement of the energy in a system and/or object.  The greater the motion/energy (and transference of motion), the greater the heat.  Heat is transferred through three different means: conduction (direct contact), convection (fluidic motion), and radiation (energy transferred through space).
