What is convection in the context of heat transfer?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

What type of heat transfer occurs when you hold an ice cube in your hand?

Back

Conduction is the type of heat transfer that occurs when you hold an ice cube in your hand, as heat is transferred from your hand to the ice.

Front

What does the law of conservation of energy state?

Back

The law of conservation of energy states that energy is not created or destroyed, but can only be transferred or transformed into other forms.

What type of heat transfer is demonstrated when you feel warmth from the sun?

Back

Radiation is the type of heat transfer demonstrated when you feel warmth from the sun, as it involves the transfer of energy through electromagnetic waves.

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.

Front

What is an example of radiation in everyday life?

Back

An example of radiation is feeling the warmth of a campfire or the sun.

Front

What role does temperature play in heat transfer?

Back

Temperature differences drive heat transfer; heat moves from areas of higher temperature to areas of lower temperature.
