Energy cannot be created or destroyed just transformed (under normal conditions)
Heat
Thermal energy that flows due to a difference in temperature. Heat flows from hot to cold.
Heat Transfer
A method by which heat flows (conduction, convection, radiation).
Conduction
Heat transfer within or between solid objects.
Convection
Heat transfer into o out fluids.
Radiation
Heat transfer de to packets of energy called photons that can travel through many substances even empty spaces.

Conductor
A material through which energy (electrical thermal or sound) can be easily transferred.
Temperature
