In this article I would like to show you the connection between energy, work and quantity of heat. This basic is relatively easy to understand and important for understanding more complex facts.
In a physical system, energy is the ability to do work . So by doing work, energy is transformed. And since always as much energy is converted as work is done, one can say that energy equals work . The SI unity of work is Joule .
The following applies: (1 Joule = 1 Newton Metre = 1 Watt Second).
Conversion of the units:
Normally the formula character is used for the work. In heating technology, however, the work is referred to as the quantity of heat and has the symbol. The physical terms energy, work and quantity of heat are therefore equal to .
Different quantities are important for determining the quantity of heat. These include, among others, the following:
You can calculate the quantity of heat (work) with the following formulas:
With this knowledge you have acquired one of the most important basics of heating technology. If you have any questions I’m looking forward to see your comments
