From the weight of the water thus obtained and the rise of temperature, the calorific value may be computed.
Fat contains more than twice the amount of energy-yielding power or calorific value of proteids or carbohydrates.
The heat contained in a pound of coal is called the "calorific value" or "heating value" of the coal.
The calorific value of the gas should be measured either by the Witz apparatus or by means of any other calorimeter.
(b) The calorific value may be taken as being one-seventh that of good steam-coal.
