How does conduction occur?

Back

Conduction occurs when heat is transferred through direct contact between materials, typically in solids.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) where warmer parts rise and cooler parts sink.

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, and does not require a medium.

Give an example of conduction in everyday life.

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of convection in cooking?

Back

Boiling spaghetti noodles in water is an example of convection, as the hot water rises and cooler water moves down.

What happens to the temperature of a substance during heat transfer?

Back

During heat transfer, the temperature of the hotter substance decreases while the temperature of the cooler substance increases until thermal equilibrium is reached.
