Answer:
- As per thermodynamic heat transfer is defined as :
Heat moves across border of system due to changes in temperature between its surrounding and system .
- It is the phenomena in which energy and entropy convey from one location to another.
- The specific mechanism are as follow :
- Convection
- Thermal
- Radiation
- Conduction
- Heat can be transffered by three ways
- conduction
- convection
- radiation
- Examples are as follow :
- Conduction : it is transfer of energy from one molecules to another.
- Convection : it is movement of heat by fluid.
- Radiation : it is transfer of heat by electromagnetic waves.
