Heat Review

What kind of heat transfer happens when the sun is heating your body?

• Conduction
• Radiation
• Convection
• Density

Which of the following is an example of convection?

• A hair dryer is drying up your hair.
• When the AC or heater changes the temperature.
• When a car engine turns hot after being turned on.
• When you are making soup and the water is rising and lowering.

When a pot is  touching a stove that is on, what heat transfer is happening?

• I don't know??????
• Radiation
• Conduction
• Convection

This is a lava lamp. When the light bulb heats the wax, the wax rises. When the wax cools, it falls. This cycle of rising/falling is an example of:

• Conduction.
• Convection.
• Radiation.

A great conductor of energy is:

• wood
• plastic
• metal
• cloth

What is NOT an example of an insulator in the kitchen?

• An oven mitt
• Pots and pans
• A wooden spoon
• A plastic measuring cup

Mittens help keep your hands warm in winter because:

• They are conductors of heat.
• They are fuzzy.
• They are conductors of electrical energy.
• They are insulators.

The plastic covering is there to:

• Provide a conductor for electrical energy to flow.
• Provide an insulator so that electrical energy will Not pass outside of the wires.
• Provide a conductor so that electrical energy can NOT flow.
• Provide an insulator so that electrical energy can flow.

The metal copper is there to:

• Provide a conductor for energy to flow from one place to another.
• Provide an insulator for energy to flow from one place to another.
• Provide an insulator to slow the flow of energy.
• Provide a conductor to slow the flow of energy.

Which is NOT an insulator.

• Wool
• Plastic
• Copper
• Glass
