How does heat t0 transfer take 

place?

Heat is a form of that can be transferred from one body to another. Heat transfer from one body to another take place when a temperature difference exists between the two objects. Temperature is the degree of hotness or coldness of body. Heat transfer can take place in three  different ways: convention, conduction and radiation. Conduction  of  heat   take place when the two objects are in contact with each other. Heat transfer,  within the body,  also  take place due to this method. In convention,  the  actual  transfer of the heat  take place when the heated molecules of the substances move actually from one place to another. No actual contact between the bodies is required for heat transfer by this process. Radiation is the transfer of heat through electromagnetic waves. No medium or contact is necessary for heat transfer of take place through radiation. The best example for this is the heat energy that we receive from the sun.
