Heat transfer

Front

What is conduction in the context of heat transfer?

Back

Conduction is the transfer of thermal energy through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is radiation in the context of heat transfer?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, which can occur in a vacuum, without the need for a medium.

Front

What is convection in the context of heat transfer?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases), where warmer areas of a fluid rise and cooler areas sink.

How does heat transfer occur when you touch a hot object?

Back

Heat transfer occurs through conduction when you touch a hot object, as thermal energy moves from the hot object to your cooler skin.

Front

What is an example of radiation in everyday life?

Back

An example of radiation is feeling the warmth of the sun on your skin, which is the result of solar radiation.

Front

What role does conduction play in cooking?

Back

Conduction plays a crucial role in cooking as heat is transferred from the hot cooking surface to the food in direct contact with it.

How does the vinyl siding of a house warp due to heat?

Back

The vinyl siding warps due to radiation when exposed to the intense heat from a nearby fire, even without direct contact.

Front

What is the difference between conduction and convection?

Back

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

Front

What is an example of convection in nature?

Back

An example of convection in nature is the formation of wind, where warm air rises and cooler air moves in to replace it.

How does thermal energy transfer in a metal spoon stirring hot soup?

Back

Thermal energy transfers through conduction as the heat from the hot soup is conducted through the metal spoon to your hand.
