Calorimetry - The Study of Heat Transfer

In short, one calorie is the specific heat of water. Since the specific heat of water is also 4.184 J/g°C, the conversion factor for calories to joules is:1 calorie = 4.184 J. In the United States, the word calorie is most often associated with food. There are some clarifications that need to be made when trying to compare the usage of the word calorie in a discussion of heat and food labels. Calorimetry - The Study of Heat Transferq = mC p T. The above equation is used to calculate the heat that is gained/lost by a substance. The variable q represents heat, measured in joules.C p represents specific heat (in J/g°C) and m is the mass of the substance in grams. Lastly, T represents the change in temperature of the substance. The temperature can be degrees Celsius or kelvin, since both scales have the same increments
