Heat Transfer: Conduction, Convection, Radiation

Front

What happens to the density of a liquid when it is heated?

Back

The density of a liquid becomes less dense when heated.

Front

Define Convection.

Back

Convection is the transfer of thermal energy in a fluid (liquid/gas) by movement of warm/cool fluids.

Front

What causes a hot air balloon to rise?

Back

A hot air balloon rises due to convection.

Front

What is the primary cause of weather systems on Earth?

Back

The primary cause of weather systems on Earth is convection.

Front

What type of heat transfer occurs through direct contact of molecules?

Back

Conduction is the type of heat transfer that occurs through direct contact of molecules.

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 heat through electromagnetic waves.

Front

Give an example of Convection in everyday life.

Back

An example of convection is the heating of water in a pot on a stove.

Front

How does heat transfer through Radiation?

Back

Heat transfer through radiation occurs without the need for a medium, such as when the sun heats the Earth.

Front

What is the role of Convection in the atmosphere?

Back

Convection plays a crucial role in the formation of clouds and weather patterns.
