Jennie L. Borders

2. Question 1
the smallest group within a crystal that retains the geometric shape of the crystal
unit cell

3. Question 2
If pressure increases, then what happens to volume?
decreases

4. Question 3 kinetic energy
the energy of an object because of its motion
kinetic energy

5. Question 4
How is evaporation a cooling process?
The particles with the most kinetic energy (the highest temperature) evaporate first. That leaves the slower (cooler) particles so the temperature is lower.

6. Question 5 boiling point
the temperature at which the vapor pressure is equal to the external pressure
boiling point

7. Question 6
What volume will 3.0 moles of oxygen occupy at 820 mm Hg and 50oC?
73.7 L

8. Question 7
an empty space with no particles and no pressure
vacuum

9. Question 8
Draw the particles of a gas.

10. Question 9
a gas escapes through a tiny hole
effusion

11. Question 10 Boyle is the VIP. Charles likes direct TV.
What is the poem that I wrote to help you remember the gas laws?
Boyle is the VIP.
Charles likes direct TV.
Gay and Lussac will TP
the house directly next to me.

12. Question 11 vapor pressure
a measure of the force exerted by a gas above a liquid
vapor pressure

13. Question 12 No volume No forces Constant motion
What are the 4 assumptions of the kinetic theory?
No volume
No forces
Constant motion
Perfectly elastic collisions

14. Question 13
particles are arranged in an orderly, 3-D repeating pattern
crystal

15. Question 14 Helium effuses 2.65 times faster than nitrogen.
Compare the rates of effusion of nitrogen gas and helium gas. (I need the sentence, not just the number.)
Helium effuses 2.65 times faster than nitrogen.

16. Question 15
the change of a substance from a solid to a vapor without passing through the liquid state
sublimation

17. Question 16
Identify the liquid on the phase diagram. B

18. Question 17
two or more different molecular forms of the same element
allotrope

19. Question 18 amorphous solid super-cooled liquid
What are the two terms that I use to describe a glass?
amorphous solid
super-cooled liquid

20. Question 19
the tendency of molecules to move toward areas of lower concentration
diffusion

21. Question 20
There is a mixture of oxygen and nitrogen gas in a container. The total pressure in the container is 3.8 atm. If the partial pressure of oxygen is 1.6 atm, then what is the partial pressure of nitrogen?
2.2 atm

22. Question 21
A sample of krypton gas at 70oC and a volume of 350mL is cooled to 38oC. What is the new volume?
317mL
