Specific heat, measured in J/kg•C, is the amount of heat energy needed to change the temperature of 1 kilogram (kg) of a substance by 1¡ Celsius. An example is the specific heat of water, which is 4190 J/kg•C. This means that if you had 1 kg of water, it would take 4190 J (joules) of heat energy to raise its temperature by 1¡C. Activity 11
