I had a test today on KMT and gases etc and want to know how I did....can you tell me if I answered these right?

1. You have two flasks under identical pressure and volume. One is CO and one is N2. Which of the following are the same?
I. molar mass
II. average kinetic energy
III. velocity of particles

A. I only
B. II only
C. III only
D. I and III only
E. I, II, and III
I put E

2. What about the particles and the container makes the pressure and temp. both increase proportionally when heated? (or something of the sort)

A. increased energy in collisons
B. increased frequency of collisons
C. decreased energy "
D. decreased freq. "
E. increased energy and freq.
I put B

3. Which of the following is NOT true when calculating H2 volume by displacement with water?

A. the temp of H2 and H20 are the same
B. the pressure of H2 is less than that of H20
C. there is a greater mass in an H20 molecule than an H2
D. there are more H2 particles than H20 particles
E. (something else that I know wasn't right)
I put D

4. If you have a sample of gas at constant volume and temp and add more of the gas at constant temp and pressure, which is true?

A. pressure increases, avg kin energy staysthe same
B. both press and avg kin en. increase
C. both the same
D pressure decreases, avg kin the same
E. avg kin dec and pressure inc
I put D

Those are just a few that I want to know if I got right...thanks for the help.
