Transfer of Thermal energy

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases). Warm fluid rises while cool fluid sinks, creating a circulation pattern.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves. It does not require a medium and can occur in a vacuum.

Front

Example of conduction in everyday life?

Back

Ironing a shirt is an example of conduction, where heat is transferred from the iron to the fabric.

Front

Example of convection in everyday life?

Back

Boiling water demonstrates convection, as warm water rises and cool water sinks.

Example of radiation in everyday life?

Back

The sun warming your skin is an example of radiation, where heat is transferred through electromagnetic waves.

Front

What happens to warm air in convection?

Back

In convection, warm air rises because it is less dense than cool air, which then sinks.

Front

What is the role of thermal energy in conduction?

Back

In conduction, thermal energy is transferred from the hotter object to the cooler object through direct contact.

Front

How does convection affect weather patterns?

Back

Convection currents in the atmosphere can lead to the formation of clouds and influence weather patterns.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, reducing the transfer of thermal energy.
