Factors affectin cooling rate

... Triple Physics has been asked to investigate the factors that affect the cooling rate of a liquid Research: There are three ways in which heat can be transferred: Conduction: Heat energy is conducted from the hot end to the cold end. It is transferred from atom to atom. At the hot end the atoms are vibrating a lot. The vibration is gradually passed along to the other atoms as they collide into each other. This happens in all substances, but in a metal something extra happens. A metal has many free-moving electrons. These free-electrons can travel through the metal, transferring the energy more quickly. Convection: The transfer of energy, by the movements of particles only in liquids and gases Radiation: Energy from the Sun reaches us after travelling through space at the speed of light. When this hits an object, some of it is taken in or absorbed. This makes the molecules vibrate more - and so
