Steaming Cup of Hot Tea - The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air. WebPrinciples of Heat Transfer. Heat is transferred to and from objects -- such as you and your home -- through three processes: conduction, radiation, and convection. Conduction is … WebSo, there are three main methods of transferring heat: radiation, convection/mass transfer, and conduction. Presumably radiation is not a major method of heat transport between the core and the crust, because it requires transparent materials (or a vacuum), and I don't think there is much of either in the mantle. darley 4 shelf trestle bookcase
