Conduction, Convection, Radiation

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, allowing heat to be transferred through empty space.

How does an iron smooth out wrinkles in clothes?

Back

An iron smooths out wrinkles by transferring heat to the clothes through conduction.

Front

How do heat lamps keep baby chickens warm?

Back

Heat lamps keep baby chickens warm by transferring heat through radiation.

Front

Why does a rock get hot during the day?

Back

A rock gets hot during the day because it absorbs heat from the sun through radiation.

Front

Why does the handle of a metal spoon warm up in hot soup?

Back

The handle of a metal spoon warms up in hot soup due to conduction, as heat transfers from the soup to the spoon.

Front

How does a chair get warm from a fireplace?

Back

A chair gets warm from a fireplace through radiation, as heat radiates from the fire to the chair.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of convection in everyday life?

Back

An example of convection is boiling water, where hot water rises to the top and cooler water sinks.
