WebA British thermal unit (Btu) is a measure of the heat content of fuels or energy sources. It is the quantity of heat required to raise the temperature of one pound of liquid water by 1 degree Fahrenheit at the temperature that water has its greatest density (approximately 39 degrees Fahrenheit). One British thermal unit (Btu) is approximately ... WebIn the derivation of , we considered only a constant volume process, hence the name, ``specific heat at constant volume.''It is more useful, however, to think of in terms of its definition as a certain partial derivative, which is a thermodynamic property, rather than as a quantity related to heat transfer in a special process. In fact, the derivatives above are …
