WebThe heating curve for water shows how the temperature of a given quantity of water changes as heat is added at a constant rate. During a phase change, the temperature of the water remains constant, resulting in a plateau on the graph. We can use the heating curve to calculate the amount of heat required to raise the temperature of the water ... Web13 de nov. de 2024 · It takes about 8 BTU to heat a gallon of water only one degree F. It only takes about 0.2 BTU to heat the same volume of air one degree F. It takes about 400 times more energy to heat water than air per unit volume. Since the heat is so concentrated in the water's volume, it's easier to insulate and keep warm because there is less … pay rate fast food https://decobarrel.com
