| B. | Evaporation |
| C. | Revolution |
| D. | Thermal Expansion |
| Answer» A. Convection | |
|
Explanation: Convection is the transfer of heat from one place to another by the movement of fluids. It is usually the dominant form of heat transfer (convection) in liquids and gases. Although often discussed as a distinct method of heat transfer, convective heat transfer involves the combined processes of conduction (heat diffusion) and advection (heat transfer by bulk fluid flow). |
