Heat Transfer Review

Check the 3 types of heat transfers.

• Conductor

• Convection

• Conduction

• Radiator

• Radiation

Conduction is the transfer of heat by

• direct contact between 2 objects.

• hot fluids rising and cool fluids sinking.

• electromagnetic waves.

Which of the following is an example of heat transfer through conduction?

• You are sitting in the sun and feel the heat on your face.

• You feel the steam rising over a pot of boiling water.

• You slide down a hot slide and the slide burns your legs when you touch it.

Where can Earth's atmosphere be heated by conduction?

• In the upper atmosphere, where warm air rises and cooler air sinks.

• On the surface of the Earth, where the air is touching the surface of the earth.

What is heat transfer?

• The transfer of heat from a cold object tho a warm object.

• The transfer of heat from one object to another.

Why is air warmer near Earth's surface?

• The sun heats Earth's surface and in turn the air above it is heated.

• Warm air is more dense and sits on top of the Earth's surface.

• Warm air is less dense and sits on Earth's surface.

Convection takes place in

• solids & liquids.

• gases & liquids.

• solids & gases.

• none of the above

When convection occurs in the atmosphere:

• warm air sinks and cool air rises.

• warm air rises and cool air sinks.

• warm and cool air sink.

• warm air rises and cool air sings.
