SP.5.1 - Heat energy is produced in many ways and flows from a hotter region or object to a cooler one.
SP.5.2 - All living organisms require a correct amount of heat.
SI.5.1 - An increase in the temperature of an object can mean that heat energy is flowing into it; a decrease of the temperature can mean that heat is flowing out of it.
SI.5.2 - We can use heat energy to drive heat engines and thus to domechanical work.
SJ.5.1 - Heat energy can be transferred from one place to another byprocesses called conduction, convection, and radiation.
SJ.5.2 - Heat energy can flow from a cooler object to a warmer one, but only with the addition of other energy.
SH.5.1 - Heat energy can only be produced by conversion from other forms of energy; it is never created from nothing.
SH.5.2 - There is a limit set on the efficiency of a heat engine.
