How much heat is required to raise the temperature of 1 pound of water by 10° F?

Heat Required to Raise Temperature of Water

The amount of heat required to increase the temperature of 1 pound of water by 10° F is 1000.

In this case, the specific heat of water is 1 calorie per gram per degree Celsius, which is equivalent to 1 calorie per 4.184 joules. When we convert this to pounds, we have to consider that 1 pound of water is equal to approximately 453.592 grams. So, when we calculate the heat required using the formula Q = mcΔT, where Q is the heat, m is the mass, c is the specific heat, and ΔT is the temperature change, we get 1 * 453.592 * 4.184 * 10 ≈ 18877.08 calories. Since 1 calorie is equal to 4.184 joules, the heat required in joules would be approximately 18877.08 * 4.184 ≈ 79051.67 joules. Finally, to convert this to kilocalories, we divide by 1000, which gives us 79.05167 kilocalories. Therefore, the amount of heat needed to raise the temperature of 1 pound of water by 10° F is approximately 79.05167 kilocalories, or simply 1000 calories.
