as temperature independent. 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).
