Definition of "heat"

Heat and temperature, although different, are intimately related. [...] For example, suppose you added equal amounts of heat to equal masses of iron and aluminum. How do you think their temperatures would change? […] if the temperature of the iron increased by 100 C°, the corresponding temperature change in the aluminum would be only 48 C°.

Heat limits the length and intensity of ship-to-ship combat. Starships generate enormous s'heat when they fire high-energy weapons, perform maneuvering burns, and run on-board combat electronics.In combat, warships produce heat more quickly than they can disperse it. As heat builds within a vessel, the crewed spaces become increasingly uncomfortable. Before the heat reaches lethal levels, a ship must win or retreat by entering FTL. After an FTL run, the ships halts, shuts down non-essential systems, and activates the heat radiation gear.
