Heat Transfer

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

Front

What are the three main methods of heat transfer?

Back

The three main methods of heat transfer are conduction, convection, and 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 through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

Which materials are good conductors of heat?

Back

Metals like copper and aluminum are good conductors of heat.

Front

Which materials are good insulators of heat?

Back

Materials like wood, plastic, and rubber are good insulators of heat.

Front

How does a hot air balloon rise?

Back

A hot air balloon rises because the heated air inside the balloon is less dense than the cooler air outside, causing it to float.

Front

What happens to ice when held in a person's hand?

Back

The heat from a person's hand transfers by conduction to the ice, causing it to melt.

Why is wood a good material for frying pan handles?

Back

Wood is a good material for frying pan handles because it does not conduct heat well, preventing burns.
