Thermal Energy Transfer

Front

What is thermal energy transfer?

Back

The process of heat moving from one object or substance to another due to a temperature difference.

Front

Define conduction in the context of thermal energy transfer.

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 movement of gas or liquid in which warmer parts move up and the colder parts move down, creating a circulation pattern.

Front

Give an example of conduction in everyday life.

Back

Ironing a shirt is an example of conduction, where heat is transferred from the iron to the fabric.

Front

What happens to particles in a substance as they heat up?

Back

As particles heat up, they gain energy and move faster, causing the substance to expand.

Front

What happens to particles as they cool down?

Back

As particles cool down, they lose energy and slow down, causing the substance to contract.

Front

What is the role of thermal conductors?

Back

Thermal conductors are materials that allow heat to pass through them easily, such as metals.

Front

What is the role of thermal insulators?

Back

Thermal insulators are materials that resist the flow of heat, such as wood or plastic.

Front

How does temperature affect the rate of thermal energy transfer?

Back

The greater the temperature difference between two objects, the faster the rate of thermal energy transfer.

Front

What is an example of convection in nature?

Back

An example of convection in nature is the movement of warm air rising and cool air sinking, creating wind patterns.
