What are you measuring when you measure heat?
You measure heat energy in units called calories. (Not to be confused with food Calories) A calorie is how much energy (energy is measured in Joules, I think.) it takes to warm 1 gram of water 1 degree Centigrade. Fact: 1,000 heat calories (small 'c') makes 1 food Calorie (large 'c') Additionally, if temperature is measured in Kelvin degrees, then its value is directly proportional to the average kinetic energy of the molecules of a substance. Temperature is not energy, it is proportional to a type of energy. Heat is energy measured in Joules or other energy units eg calories. Heat is a measurement of some of the energy in a substance. When you add heat to a substance, you are adding energy to the substance. This added energy is leads to an increase in the kinetic energies of the molecules of the substance. The energy can break bonds rather than increase temperature.
