U3 SWYK LGD- Heat Transfer

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. For example, when you touch a hot stove, heat transfers from the stove to your hand.

Front

What is convection?

Back

Convection is the transfer of heat in fluids (liquids and gases) where warm areas rise and cool areas sink, creating a circulation pattern. An example is warm air rising in a room.

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves, which can occur in a vacuum. An example is the heat from the Sun reaching the Earth.

Front

How does heat transfer from the Sun to the Earth?

Back

Heat from the Sun reaches the Earth through radiation.

Front

What happens to warm air in a room?

Back

Warm air rises to the top of the room, while cooler air sinks, creating convection currents.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a pot of hot soup.

Front

What is an example of convection?

Back

An example of convection is the way warm air rises and cool air sinks, creating wind.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the Sun on your skin.

Front

What type of heat transfer occurs in fluids?

Back

Convection occurs in fluids, such as when warm air rises and cold air sinks.

Front

What is the main difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.
