Explain the conduction, convection and radiation with the
help of example from our surroundings
Answers
Conduction:
Touching a stove and being burned
Ice cooling down your hand
Boiling water by thrusting a red-hot piece of iron into it
Convection:
Hot air rising, cooling, and falling (convection currents)
An old-fashioned radiator (creates a convection cell in a room by emitting warm air at the top and drawing in cool air at the bottom).
Radiation:
Heat from the sun warming your face
Heat from a lightbulb
Heat from a fire
Heat from anything else which is warmer than its surroundings.
Explanation:
convection:transfer heat energy through games and liquid state.
example:boiling milk or water .
conduction:heat energy form one solid to another.
example:a metal spoon .
radiation:transfer heat in the form of waves or particles through places where there no molecules.
example:ultra violet radiation and x ray
