Today I would like to introduce the specific heat capacity to you in a slightly smaller article. The specific heat capacity
indicates the quantity of heat
that a substance can release or absorb in relation to its mass
when the temperature changes. The temperature change is given as temperature difference
in Kelvin
.
The specific heat capacity indicates the amount of energy required to increase 1 kg of a substance by 1 Kelvin. The unit for the specific heat capacity is:
.
The specific heat capacity can be determined as follows:
![]()
![]()
The specific heat capacity of water, for example, is at a temperature of 20°C: ![]()
![Rendered by QuickLaTeX.com \[\boxed{c_{Water}=4182\frac{J}{kg\cdot K} = 1,1617\frac{kWh}{m^3\cdot K} = 0,00116\frac{kWh}{kg\cdot K}}\]](https://cdn.buildingservicestutor.com/wp-content/ql-cache/quicklatex.com-8f3885355d395a7352c37f16f5290c48_l3.png)
For instance, to calculate the quantity of heat for a change in the temperature of heating water, the temperature spectrum from 0 to 100 °C is simplified to
or .
In the following link you will find an overview of different substances and their specific heat capacity: Table of specific heat capacities
If you have any questions I’m looking forward to see your comments
