Heat Transfer in Water, Air, and Land

Heat Transfer

​S6E4. Obtain, evaluate, and

communicate information about

how the sun, land and water

affect climate and weather.

S6E4.b. Plan and carry out an

investigation to demonstrate how

energy from the sun transfers

heat to air, land and water at

different rates.

Heat Tranfser

how is energy is transferred from an object with more energy to an object or area with less energy

Heat Transfer

HOT --> COLD!!! Hot particles have lots of energy and are trying to move!

​

As they ​bump into each other they start to spread apart and cool down

Multiple Choice

How does heat transfer?

• Hot to cold

• Cold to hot

3 Types of Heat Transfer:

• Conduction

• Convection

• Radiation

Conduction

through DIRECT CONTACT!

conductor: transfers heat well (metal)

insulator: does not transfer heat well (wood, plastic, etc.)

Multiple Select

Which of the following are good conductors? (select all that apply)

• Copper

• Plastic

• Wood

• Steel

Convection

by the movement of a fluid (liquid or gas).

​

When a fluid is HEATED its particles SPEED UP

and move APART, making it LESS dense.

​

COOLED its particles SLOW DOWN

and move TOGETHER, making it MORE dense

​

This creates a CONVECTION CURRENT

transferring heat throughout the fluid.

Radiation

by electromagnetic (EM) waves.

​

*This is the ONLY method of heat transfer that does NOT require matter (can travel in space)!*

​

This is how the ​energy from the SUN gets to Earth :)
