convection of heat give me appratus, procedure and result.
Answers
Answer:
Convection, process by which heat is transferred by movement of a heated fluid such as air or water. Natural convection results from the tendency of most fluids to expand when heated—i.e., to become less dense and to rise as a result of the increased buoyancy.
Result:
This type of heat transfer is called convection. The fluid above a hot surface expands, becomes less dense, and rises. ... As the space heater heats the air surrounding it near the floor, the air will increase in temperature, expand, and rise to the top of the room.
Apparatus:
A space heater is a classic convection example. As the space heater heats the air surrounding it near the floor, the air will increase in temperature, expand, and rise to the top of the room. This forces down the cooler air so that it becomes heated, thus creating a convection current.
Procedure:
What is Convection? Convection combines conduction heat transfer and circulation to force molecules in the air to move from warmer areas to cooler ones. As the molecules closest to the heat source become warm, they rise and are replaced by cooler molecules.
