Circle the letter of each sentence that is true about ideal gases and real gases. a. An ideal gas does not follow the gas laws at all temperatures and pressures. b. An ideal gas does not conform to the assumptions of the kinetic theory. c. There is no real gas that conforms to the kinetic theory under all conditions of temperature and pressure.

What would be the units for R if P is in pascals, T is in kelvins, V is in liters, and n is in moles?

Circle the letter next to the correct description of how the combined gas law must be modified to introduce the number of moles. a. Multiply each side of the equation by the number of moles. b. Add the number of moles to each side of the equation. c. Divide each side of the equation by the number of moles.

Circle the letter next to each sentence that is true concerning the compressibility of gases. a. The large relative distances between particles in a gas means that there is considerable empty space between the particles. b. The assumption that particles in a gas are relatively far apart explains gas compressibility. c. Compressibility is a measure of how much the volume of matter decreases under pressure. d. Energy is released by a gas when it is compressed.

Circle the letter next to each sentence that correctly describes how gases behave when the temperature increases. a. The average kinetic energy of the particles in the gas increases as the particles absorb energy. b. Faster-moving particles impact the walls of their container with more force, exerting greater pressure. c. When the average kinetic energy of the enclosed particles doubles, temperature doubles and the pressure is cut in half.

At a specified temperature and pressure, is the number of moles of gas in a sample directly proportional or inversely proportional to the volume of the sample?

Why do three quantum numbers come out of the Schrödinger theory (rather than, say, two or four)?

What do we mean by cognitive learning, and how does it vary from the conditioning theory approach to learning?

Use a Venn diagram like the one below to compare and contrast the goals, methods, and outcomes of Keynesian theory and monetarism.

Phosphorus trifluoride, $\mathrm{PF}_3$, has $\mathrm{F}-\mathrm{P}-\mathrm{F}$ bond angles of $97.8^{\circ}$. (a) How would VB theory use hybrid orbitals to explain these data? (b) How would VB theory use unhybridized orbitals to account for these data? (c) Do either of these models work very well?

According to the rational voter theory, will the following increase or decrease voter turnout?

c. The number of polling stations increases.

Earth rotates much faster than Venus. How does the giant impact theory of the Moon account for this fact?

State two principles from Dalton’s atomic theory that have been revised as new information has become available.

Conduction of an electric current is a general property associated with metals. How does the band theory for metallic bonding explain conductivity?
