Answer:
1.Thermal conduction is the transfer of internal energy by microscopic collisions of particles and movement of electrons within a body.
2.Convection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity.
3.Radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium.
