Conduction, Convection, Radiation Review

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one, like when a metal spoon gets hot after being in a pot of boiling water.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer, less dense areas of a fluid rise and cooler, denser areas 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, which is why heat from the Sun can reach the Earth through the vacuum of space.

Front

What are conductors?

Back

Conductors are materials that allow heat to flow through them easily. Examples include metals like copper and aluminum.

Front

What are insulators?

Back

Insulators are materials that do not allow heat to flow through them easily. Examples include rubber, wood, and plastic.

Front

How does heat energy reach the Earth from the Sun?

Back

Heat energy from the Sun reaches the Earth through radiation.

Front

What happens to a spoon left in a hot pot?

Back

The spoon becomes hot due to conduction, as heat transfers from the hot pot to the spoon.

Front

Why does a dog lay next to a wood stove?

Back

The dog lays next to the wood stove to absorb heat through radiation.

Front

What is an example of convection in everyday life?

Back

An example of convection is when warm air rises and cool air sinks in a room, creating a circulation of air.

Front

What is the role of insulation in buildings?

Back

Insulation helps to keep buildings warm in winter and cool in summer by reducing heat transfer.
