Answer to Question 1

The specific heat of a substance can be determined by measuring the masses and temperature changes of the objects involved. Typically a substance of known mass and temperature is put into a quantity of water in a calorimeter. The water is at a different temperature from that of the substance, usually a lower one. The principle of the conservation of energy is then applied to determine the substance's specific heat. This method is called the method of mixtures.
