Unit 5 Workman Science Review

Front

What is conduction?

Back

Conduction is the transfer of heat through a solid material without the movement of the material itself. It occurs when two objects at different temperatures are in direct contact.

Front

What is convection?

Back

Convection is the transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself. Warmer, less dense fluid rises while cooler, denser fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light. It does not require a medium to travel through, allowing heat from the Sun to reach Earth.

Front

How does heat energy reach the Earth from the Sun?

Back

Heat energy from the Sun reaches the Earth through radiation.

Front

What is the primary method of heat transfer in solids?

Back

The primary method of heat transfer in solids is conduction.

Front

How does heat move?

Back

Heat moves from warm places to cooler places.

Front

What type of materials conduct heat best?

Back

Solids, especially metals, conduct heat best due to closely packed particles.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is when a metal spoon gets hot after being placed in a pot of boiling water.

Front

What is an example of convection?

Back

An example of convection is the way warm air rises and cool air sinks in a room, creating a circulation of air.

Front

What is an example of radiation?

Back

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