Conduction, Convection, & Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

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

Front

What is radiation?

Back

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

Front

How does heat transfer occur in a metal spoon placed in hot soup?

Back

Heat transfers from the hot soup to the spoon through conduction.

Front

What happens to the temperature of a substance when it absorbs heat?

Back

The temperature of the substance increases as it absorbs heat.

Front

What is an example of convection in everyday life?

Back

An example of convection is the warm air rising and cool air sinking in a room, creating air circulation.

Front

How does heat flow when holding a hot cup of tea?

Back

Heat flows from the hot cup of tea to the cooler hand holding it.

Front

What is an example of radiation?

Back

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

Front

What is the role of convection in weather patterns?

Back

Convection helps to circulate warm and cool air, influencing weather patterns and creating wind.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.
