|
|
radiation
|
|
|
conduction

Explanation:
Detailed explanation-1: -The heat energy can be transferred by the process of convection by the difference occurring in temperature between the two parts of the fluid. Due to this temperature difference, hot fluids tend to rise, whereas cold fluids tend to sink. This creates a current within the fluid called a convection current.
Detailed explanation-2: -Convection is the transfer of thermal energy by the movement of a liquid or gas. Convection works when a liquid or gas is unevenly heated. Hot liquids (and gases) are less dense and rise, causing. The warmer section of the material will rise while the cooler part sinks.
