Question

what is convention method of heat transfer? how does Convection take place?​

Answer 1

Explanation:

When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. This type of heat transfer is called convection. The fluid above a hot surface expands, becomes less dense, and rises. ... A space heater is a classic convection example.

Answer 2

Convection is the transfer of heat due to the bulk movement of molecules within fluids (gases and liquids), including molten rock (rheid). Convection includes sub-mechanisms of advection (directional bulk-flow transfer of heat), and diffusion (non-directional transfer of energy or mass particles along a concentration gradient).
