Etymology 1
From (etyl) hete, from (etyl) .Noun
- 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°.
