Heat transfer

Heat transfer and thermodynamics

◉ Heat: The form of energy that can be transferred from one system to another
as a result of temperature difference.
◉ Thermodynamics is concerned with the amount of heat transfer as a system
undergoes a process from one equilibrium state to another.
◉ Heat Transfer deals with the determination of the rates of such energy
transfers as well as variation of temperature.
◉ The transfer of energy as heat is always from the higher-temperature
medium to the lower-temperature one. Heat transfer stops when the two
mediums reach the same temperature.
◉ Heat can be transferred in three different modes: conduction, convection,
and radiation
