Unit 4 Study Guide

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 parts of the fluid rise while cooler parts sink, creating a circulation pattern.

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 a vacuum.

Front

How does heat travel between objects?

Back

Heat travels from hot objects to cold objects until thermal equilibrium is reached.

Front

What is an example of Conduction?

Back

An example of conduction is touching a hot stove and burning your hand.

Front

What is an example of Convection?

Back

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

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 when cooking on a stove?

Back

Conduction occurs when cooking on a stove, as heat is transferred from the burner to the skillet.

Front

What type of energy conversion occurs in a wind turbine?

Back

A wind turbine converts mechanical energy from the wind into electrical energy.

Front

What happens to heat when two objects at different temperatures touch?

Back

Heat flows from the hotter object to the cooler object until they reach the same temperature.
