100

This is the process of a liquid turning into a gas at the surface.

Evaporation

100

This type of heat transfer happens through direct touch, like burning your hand on a hot taypan.

Conduction

100

In this state of matter, particles are packed tight and only vibrate in place.

Solid

100

Materials like metal that allow heat to pass through them easily are called this.


Conductors 

100

This is the tool used to measure the average kinetic energy (heat) of a substance.

Thermometer 

200

When water vapor touches a cold soda can and turns back into liquid droplets, it is called this.

Condensation

200

This method of heat transfer moves through gases and liquids in circular patterns called "currents."

Convection 

200

When you add heat to a substance, do the molecules move faster or slower?

Faster

200

A material like wool, rubber, or wood that slows down the flow of heat.

insulators 

200

Which is more dense: a solid or a gas? Explain why using the word "particles."

Solid

300

True or False: Energy is added to water to make it evaporate.

True

300

This is the only form of heat transfer that can travel through the empty vacuum of space.

Radiation 

300

his state of matter has a definite volume but takes the shape of its container.

Liquid

300

Why are most frying pans made of metal but have plastic or wooden handles?

Because metal is a conductor and plastic/wood are insulators.

300

If you put a wooden spoon and a metal spoon in a pot of boiling water, why does the metal spoon feel hotter if they are both in the same temperature water?

The metal spoon conducts heat to your hand faster; the wood is an insulator.

400

Clouds being created is due to 

Condensation 
400

When warm air rises and cool air sinks, it creates this type of cycle.

Convection Current 

400

This state of matter has no definite shape and no definite volume; its particles fly everywhere!

Gas

400

A winter coat doesn't actually "give" you heat; instead, it does this to your body heat.

What is traps it (prevents it from escaping)

400

In a house with a fireplace, why do the upstairs bedrooms often stay warmer than the downstairs rooms, even if the fire is downstairs?

Because of convection (warm air is less dense and rises).

500

You see "fog" on the inside of a window on a cold day. Is the water vapor coming from the air inside the house or the air outside?


Inside 

500

The sun warming your face and a microwave cooking popcorn are both examples of this.

Radiation 

500

Heat always moves in this direction (choose: Hot to Cold OR Cold to Hot).

Hot to cold

500

What material is best for keeping items hot and why

Metal because it is a good conductor of heat
