1
Solid to liquid is:
Deposition
Melting
Freezing
Sublimation
2
When ice melts, what happens?
Energy flows from the ice into the surroundings.
The temperature of the ice increases as it melts.
Energy flows from the surroundings into the ice.
Energy is not flowing.
3
Why is the volume of a liquid constant?
Because a compressible liquid violates the laws of physics.
Because the atoms are already close together, making it incompressible.
Because the atoms are far apart, and they want to stay that way.

Unknown
300 K
150 mL
11
Which of the following is NOT a unit of pressure?
Pascal (Pa)
Newton (N)

Atmosphere (atm)
12
Which states of matter have atoms that are in some sort of motion at all times?
Gases
Solids
Solids, liquids, and gases
Liquids
13
Why can scientists ignore the forces of attraction in a gas?
The atoms are not attracted, they are repelled.
The atoms are unreactive.
The atoms never collide with each other.
The atoms are moving too fast and are too far apart.
14
Raising the temperature of a gas will increase the pressure if the volume:
changes.
Acutally, there will be no effect.
remains constant.

19
Gas pressure is caused by:
Gnomes.
The forces of attraction between the gas molecules.
The force of attraction in the nucleus of the atoms.
Collisions between the gas molecules and the walls of the container.
20
The reverse of vaporization is:
Freezing
Melting
Condensation
Boiling
21
