The heat is transferred via three modes conduction, convection, and radiation depending upon the state of medium.
1. Conduction: A hamburger sizzles on a frying pan.
2.Convection: Warm air moves from the beach toward the ocean.
3. Radiation: Direct sunlight heats the sidewalk.
Heat energy can be transferred in three forms, depending upon the state of the medium.
Conduction:
The transfer of heat energy between two solid substance when they are in direct contact.
For example-hamburger on the pan.
Convection:
The transfer of heat in the liquid or gaseous medium.
For example- the movement of air towards the beach.
Radiation:
The transfer of heat in the form of electromagnetic waves.
For example- Hot air oven.
Therefore, the heat is transferred via three modes conduction, convection, and radiation.
