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

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.
