5
The temperature where a gas cannot be a liquid despite pressure is called:
critical temperature
deposition
phase change
triple point

the temperature stays the same
the number of particles decrease
the pressure increases
none of the above
8
How do you find the 'normal' freezing point on a phase change diagram?
Where all three phase exist
At 0 degrees Celicius
At absolute zero
At the temperature when the pressure is 1 atm

11
The distance between particles:
is greatest in a liquid
is the same in all states of matter
is greatest in a solid
is greatest in a gas
12
Kinetic energy:
decreases when temperature increases
is unaffected by temperature
increases when temperature decreases
inceases when the temperature increases
13
The lines on the heating curves that are flat:
show an increase in kinetic energy

decrease in potential energy
14
What is NOT part of the Kinetic Molecular Theory?
Gas collisions are inelastic
Gases are not attracted to each other
The temperature of the gas depends on the kinetic energy
Gases are compressible
