Solution
- Convection is the transfer of heat through the movement of fluids (liquids or gases).
- In the process of convection, heat energy is transferred by the mass motion of molecules within the fluid.
- As the fluid is heated, it becomes less dense and rises, while the cooler fluid sinks, creating a convection current.
