Conduction, Convection, Radiation

Front

What is convection?

Back

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

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight, which can travel through a vacuum.

Front

How many kinds of heat transfer are there?

Back

There are three kinds of heat transfer: conduction, convection, and radiation.

Front

In which direction does heat transfer?

Back

Heat transfers from hot to cold.

Front

What is an example of conduction?

Back

Ironing a shirt is an example of conduction.

Front

What is an example of convection?

Back

Boiling water is an example of convection, where hot water rises and cold water sinks.

Front

What is an example of radiation?

Back

The warmth felt from the sun is an example of radiation.

Front

What happens to air when it is heated?

Back

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

Front

What is the role of the Law of Conservation of Energy in heat transfer?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transferred or transformed.
