WebHeat Transfer Concepts Draft 2, 10/01/06 Part 1 Introduction There are three different types of heat transfer: conduction, convection, and radiation. A temperature difference must exist for heat transfer to occur. Heat is always transferred in the direction of decreasing temperature. Temperature is a scalar, but heat flux is a vector quantity. WebEnergy is always exchanged between a system and its surroundings, although this process may take place very slowly. A truly isolated system does not actually exist. An insulated thermos containing hot coffee approximates an isolated system, but eventually the coffee cools as heat is transferred to the surroundings. ... When heat is transferred ...
