energy cannot be created or destroyed (under normal conditions
heat

heat transfer
a method by which heat flows (conduction Convection radiation)
conduction
heat transfer within or between solid objects
convection
heat transfer into or of out fluids
radiation
heat transfer due to packets of energy called photons that can travel through many substances even empty space
