1. The kinetic-molecular theory states that all particles of matter are always in motion.
a.) True
b.) False
Answer: True
2. Gases have molecules in rapid random motion.
a.) T
UGH I don't know why it did that.
2. ...
a.) True
b.) False
Answer: a
I think 2 is true.
I have mixed feelings about 1. I don't think the KMT addresses anything other than gases but the use of the word "all" implies the KMT applies to solids, liquids, and gases. Having said all of that, it is true that even solids have molecules that are moving (although perhaps ever so slightly) so I would go with true for the answer. The question is worded funny. I don't know if that is on purpose or not.

b.) False
Answer: True
3. The temperature of a gas is directly proportional to its average kinetic energy.
a.) True
b.) False
Answer: True
4. The volume of a gas is inversely proportional to its pressure, assuming constant temperature.
a.) True
b.) False
Answer: True
5. The ideal gas law equation is PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature.
a.) True
b.) False
Answer: True
rue
b.) False
Answer: True
To get the answer, we can look at the definition of gases and their behavior. Gases are composed of molecules that are constantly moving and colliding with one another. This motion is random and rapid, which is consistent with the statement that gases have molecules in rapid random motion.
