Thermal energy that flows from something of high temp. to something of low temp.
Heat mass specific change heat in temp.
Examples: Heat from the sun, heat lamps used in restaurants
“Thermal energy can flow from colder objects to hotter objects only if work is done.”
Thermal energy that is not converted into work is called waste heat.
Waste heat is lost to the environment.
