Convection, Conduction, Radiation Practice

Front

What is convection?

Back

Convection is the movement of gas or liquid in which warmer parts move up and the colder parts move down, transferring heat.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through space without the need for a medium, often through electromagnetic waves.

Front

Give an example of convection.

Back

Movements of water in a pot when heated, where warm water rises and cool water sinks.

Front

Give an example of conduction.

Back

A slice of bacon frying in a pan, where heat is transferred from the pan to the bacon.

Front

Give an example of radiation.

Back

Cooking a hotdog in a microwave, where heat is transferred through microwaves.

Front

What happens to warm air in convection?

Back

Warm air rises because it is less dense than cooler air.

Front

What happens to cool air in convection?

Back

Cool air sinks because it is denser than warm air.

Front

What is the primary method of heat transfer in liquids?

Back

Convection is the primary method of heat transfer in liquids.

Front

What is the primary method of heat transfer in solids?

Back

Conduction is the primary method of heat transfer in solids.
