Chapter 13 and 14 Review Game Jennie L. Borders

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

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

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

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.

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

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

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

Question 8 Draw the particles of a gas.

Question 9 a gas escapes through a tiny hole effusion

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.

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

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

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

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.

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

Question 16 Identify the liquid on the phase diagram. B

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

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

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

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

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