Explain how thermal energy is transferred through convection
How is convection different than conduction?
Give two examples of convection currents that you might encounter in everyday life.
Answers
Answer:
Q1)Thermal energy is transferred from hot places to cold places by convection. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. ... Another good example of convection is in the atmosphere. The earth's surface is warmed by the sun, the warm air rises and cool air moves in.
Q2)In conduction, the heat transfer takes place between objects by direct contact. In convection, the heat transfer takes within the fluid. In radiation, the heat transfer occurs through electromagnetic waves without involving particles. The heat transfer takes place due to the difference in temperature.
Q3)Examples:Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. ...
Radiator - Puts warm air out at the top and draws in cooler air at the bottom.
