…The unit of specific heat is usually the amount of heat required to raise the temperature of 1g of a substance by 1K, expressed in cal, i.e. cal/K・g. The product of specific heat and the mass of a substance is called heat capacity, and for gases, the heat capacity per mole is often used, which is called molar specific heat. Specific heat varies depending on temperature and pressure even for the same substance, and can vary greatly depending on whether the substance is in a gas, liquid, or solid state. … *Some of the terminology that mentions "molar heat" is listed below.

…比熱の単位としては通常,1gの物質を1K上げるのに要する熱量をcalで表したもの,すなわちcal/K・gが使われる。比熱と物質の質量との積を熱容量といい,気体に対しては,1molに対する熱容量を用いることが多く,これをモル比熱molar heatという。 比熱は同じ物質でも温度や圧力によって異なり,とくに物質の状態が気体,液体,固体であるかによって大きく異なる。… ※「molar heat」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
