Huff Heat Transfer 5.P.3.1

Front

What is conduction?

Back

Conduction is the transfer of heat 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 heat through the movement of fluids (liquids or gases). It occurs when warmer parts of a fluid rise and cooler parts sink.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through, such as air or water.

Front

Give an example of conduction.

Back

Touching a hot stove and getting burned is an example of conduction.

Front

Give an example of convection.

Back

Boiling water in a pot is an example of convection, as the hot water rises and cooler water sinks.

Front

Give an example of radiation.

Back

Getting warm from lying in the sun is an example of radiation.

Front

Why does a metal pot get hot on a stove?

Back

A metal pot gets hot on a stove due to conduction, as heat transfers from the stove to the pot.

Front

What safety item should you use when handling a hot pot?

Back

You should use a pot holder to protect your hands from burns caused by conduction.

Front

How does ice melt in a person's hand?

Back

Ice melts in a person's hand because heat from the hand transfers to the ice by conduction.

Front

What is the main difference between conduction and convection?

Back

Conduction involves direct contact between materials, while convection involves the movement of fluids.
