Quantity of heat in water at different temperatures.—Quantity of heat may be measured by heating effect, so that we can say that the quantity of heat in a vessel of water depends upon the 7nass of the water and its tetnperature. If, for the sake of simplicity, we imagine that water at 0° C. contains no heat, then it may be said that the quantity of heat in 100 grams of water at 40° C. is twice as much as in 100 grams at
