Document Summary

Law of conservation of energy: energy can never be created of destroyed. But can be transformed from one form to another and transferred from one object to another. Energy can be transferred in two ways: as heat conduction convection radiation, as work. Heat is energy being transferred as a result of temperature difference. Addition of heat causes molecules to move faster- kinetic energy. Recall that temperature is the measure of average speed of molecules. Internal energy is the total energy contained in the molecules of a substance. C=the amount of heat in joules required to raise the temperature of 1 kg of substance by 1k. Latent heat: heat absorbed or released by a change in phase, energy transferred but there is no change in temperature. Melting, evaporation, sublimation: absorb heat, the heat become latent heat. The amount of heat associated with the phase change of a substance between liquid and gas.
