Which state of matter has particles which only vibrate?
solids

100

What is it called when matter changes from a solid to a liquid?
melting

100

What do you use to measure temperature?
a thermometer

100

What are the three types of heat transfer?
radiation, convection, conduction

200

There is ________ between all particles.
space

200

Which state of matter takes the form of the container it is in?
liquid

200

What is it called when a gas changes to a liquid?
condensing

200

What units do you use to measure temperature?
degrees celsius or degrees fahrenheit

200

Warming your hands over a fire is an example of which type of heat transfer?
radiation

300

What are all particles always doing?
Moving

300

Which state of matter does not flow?
a solid

300

What is it called when a liquid becomes a solid?
freezing

300

What is heat?
Heat is energy.

300

Cooking bacon in a frying pan is an example of which type of heat transfer?
conduction

400

When heat is lost particles ___________ and then the object _______________.
slow down.........contract

400

Which state of matter has particles separated by the most amount of space?
a gas

400

What is it called when a solid becomes a gas?
sublimation

400

When you add heat to matter does it expand or contract?
it expands

400

Heating a room through vents is an example of which type of heat transfer?
convection

500

What happens to particles when heat (energy) is added? What happens to the object?
They speed up. The object expands.

500

Which state of matter generally contains the most heat?
gas

500

Why does the temperature plateau during boiling and melting?
It plateaus because energy is used to change the state not make the particles move quicker. That is, energy is used to break bonds or free particles from the liquid's surface.

500

What happens at Zero Kelvin?
All particles stop vibrating.

500

The Earth is heated from the inside through which type of heat transfer?
convection
