Specific heat capacity, also known as specific heat
capacity, is the heat capacity of a unit mass of material,
even if the unit mass object changes the unit temperature
of the absorption or release of internal energy. Specific
heat capacity is a physical quantity that represents the
thermal properties of a substance. It is usually represented
by the symbol C.
The unit of specific heat capacity is a composite unit.
In the international system of units, the main unit of
energy, work and heat is Joule, and the main unit of temperature
is Kelvin. Therefore, the international unit of specific
heat capacity is J/(kg·K), which is read as "Joule/kilogram Kelvin".
The words in (()) can be omitted.)
Common units: J/(kg·℃), J/(g·℃), kJ/(kg·℃), cal/(kg·℃), kcal/(kg·℃), etc.
It should be noted that centigrade and Kelvin are only
different in terms of temperature scale, and are equivalent
in terms of the magnitude of temperature difference. Therefore,
the ℃ and K in these units can be arbitrarily replaced with
each other. For example, "coke per kilogram centigrade" and
"coke per kilogram on" are equivalent.
Specific heat capacity is a physical quantity indicating the
ability of an object to absorb (or dissipate) heat.
In this calculator, the specific heat capacity unit (by weight)
can be calculated by inputting a numerical value and selecting
the conversion unit (such as kg/m3).
