Conduction, convection, and Radiation Practice

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids. Example: A metal spoon heating up in a bowl of hot soup.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Example: Boiling water where hot water rises and cooler water sinks.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum. Example: Feeling warmth from the sun.

Front

What is an insulator?

Back

An insulator is a material that reduces the flow of heat. Example: Wood and rubber are good insulators.

Front

What is a conductor?

Back

A conductor is a material that allows heat to flow through it easily. Example: Metals like copper and aluminum.

Front

What is heat?

Back

Heat is the flow of energy from an object at a higher temperature to an object at a lower temperature.

Front

How does heat transfer occur in boiling water?

Back

Heat transfer in boiling water occurs primarily through convection.

Front

What is the role of a radiator?

Back

A radiator is a device that transfers heat from hot water or steam to the air in a room, typically using convection.

Front

What happens to air when it is heated?

Back

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

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection involves the movement of fluids.
