Earn robux onlineNov 12, 2019 · The specific heat capacity of pure water is 4200 Jkg-1 K-1, but since I used tap water in my experiment, I expect the average value of my experiment to be bigger than the normal value. Historically, heat (q) was measured in terms of calories. The calorie was defined as the amount of heat required to raise the temperature of 1 gram of water by 1 ºC from 14.5 ºC to 15.5 ºC at 1 atmosphere pressure. With this definition, the specific heat of water is 1.00 cal/(g · ºC). This is described in the equation ΔQ = m c ΔT, where c is the object’s specific heat capacity. Heat can be measured in calories, where one calorie is the amount of heat required to raise the temperature of one gram of water one degree Celsius.
