Use the following equation to determine the amount of heat energy that is required to increase the temperature of the water in joules.
Q = mass * specific heat * (Tf – Ti)
The specific heat of water is 4,186 J/(kg * ˚C). The mass must be in kilograms.
Q = 0.831 * 4,186 * (22 – 9) = 45,221.358 J
To covert to kilojoules, divide this number by 1000.
