What are the three ways of heat transfer in the automotive?

Heat and Thermal energy is transferred between one object to another in three different ways. 

• Heat can be transferred by Conduction, it is transferred between two objects that have contact with each other.
• Secondly Heat also can be transferred by convection, Heat is transferred from a solid to a fluid substance such as water, air and coolant. There is a circulation of the heat in liquid or gas.
• Lastly the heat can be transferred by radiation, heat is transferred from a solid to air as rays of heat. heat is measure in wavelengths. the hotter the temperature of an object, the higher the frequency of radiation there is.
