Energy Transfer and Temp Review

The AMOUNT of matter has an affect on thermal energy transfer because

• Different amounts of water have different density.

• Different amounts of water have different temperatures.

• Different amounts of water take longer/slower to transfer thermal energy.

• Different amounts of matter DO NOT affect thermal energy transfer.

The type of material DOES have an effect on thermal energy transfer because:

• items that have different DIFFERENT density transfer energy at different rates.

• items have different amounts of kinetic and potential energy.

• items have different colors and shapes.

• items have different temperatures and take time to reach room temperature.

When an object warms up

• thermal energy increases

• thermal energy decreases

• potential energy increases

• potential energy decreases

The environment DOES have an affect on thermal energy transfer because:

• Environment DOES NOT have an affect on thermal energy transfer.

• Cold environments change temperature at different rates than a warm environment.

• The environment must be cold for thermal energy to change.

• Each environment has different amounts of density.

Insulators slow down thermal energy transfer because:

• They are less dense and transfer energy slower.

• They are more dense and transfer energy faster.

• They actually do not slow down thermal energy.

• They are made of metal which is bad at transferring energy.
