「熱容量」及「比熱容量」有什麼分別?

比熱容量是指某一單位的某物質提升一度所需的能量
如1kg的水的比熱容量為4200Jkg^-1度^-1
熱容量則是指某物件提升一度所需能量,不考慮質量
如2kg的水的熱容量為8400J

熱容量(C)
當物質的溫度升一度所需的能量
熱容量=能量/溫差
比熱容量(c)
把1kg的物質的溫度升一度所需的能量
比熱容量=能量/質量*溫差

Simply speaking, "specific heat capacity" (比熱容量) is used for a specific susbtance, e.g. water, glass, wood, iron, ....etc. Difference substances have different specifc heat capacities.

"Heat capacity"(熱容量) is used, not only for a specific sbstance, but also for a given article.
For example, an iron knife and an iron pot, they have the same specific heat capacity (because of same substance), but different "heat capacity" because of different mass (i.e. diffierent article).
