Conduction, Convection, Radiation

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases) where hot fluid rises and cold fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves, such as light or infrared radiation.

Front

How does a pot get hot on a stove?

Back

The pot gets hot due to conduction, as heat is transferred from the stove to the pot through direct contact.

Front

What is an example of radiation?

Back

An example of radiation is the heat from the sun warming the Earth.

Front

What happens to air when it is heated?

Back

When air is heated, it expands, becomes less dense, and rises.

Front

What is an example of convection?

Back

An example of convection is water boiling in a pot, where hot water rises and cold water sinks.

Front

What is the best example of conduction?

Back

An egg cooking in a frying pan is the best example of conduction.

Front

What is the definition of convection?

Back

Convection is when a hot liquid or air expands, becomes less dense, and rises, while cooler liquid or air becomes more dense and sinks.

Front

How does a microwave transfer heat?

Back

A microwave transfers heat mainly through radiation.
