Heat transfer is a process in which energy in the form of heat energy is exchanged between materials that are at a different temperature. Heat is generally transferred by conduction, convection, radiation and evaporation. All of these processes can all happen simultaneously but it is likely that one will give the greater heat exchange. Plan: These are the measurements that I intend to make: * Measure the temperature every minute for 5 minutes * Record the temperature of the substance before being used and then keep this as starting temperature * Record the temperature every minute * Make sure that all substances are 100cm3 * To test different substance and different containers Variables: These are factors that may affect how long a substance will maintain its temperature. * Size of Container * Different Materials * Different Substances *...
