Answer;
The shape of convection current is circular
Explanation;
- Convection is type of heat transfer which involves the transfer of thermal energy in fluids, that is gases and liquids.
- Convection creates convection currents which helps in the distribution of thermal energy in all parts of a fluid. The convection currents occurs in a circular motion, such that heat is transferred from the hotter parts of a fluid to the cold parts of a fluid, until all the fluid attains the same temperature.
- The convection currents that aid in the transfer of thermal energy in fluids are created by the temperature differences together with density differences in fluids.
