Match the type of heat transfer to the example.

Convection

-A hamburger sizzles on a

frying pan.

•Radiation

-Warm air moves from the

beach toward the ocean.

•Conduction

-Direct sunlight heats the

sidewalk.

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.

Explanation:

Heat energy can be transferred in three forms which depends on the state of the medium as:

1. Conduction: The transfer of heat energy between two solid substance by direct contact between them like the case of hamburger on the pan.

2. Convection: The mode of heat transfer in the liquid or gaseous medium like in the movement of air towards the beach.

3. Radiation: When the heat is transferred in the form of electromagnetic waves like in the case when the sidewalk is heated by the sunlight which travels as EM waves.
