Which of the following effects will make PV/nRT less than one for a real gas?

A) The gas molecules are large enough to occupy a substantial amount of space.
B) A large number of molecules have speeds greater than the average speed.
C) The gas molecules have a very low molar mass.
D) The gas molecules attract one another.
E) None of these.

I understand why choice D is right, but shouldn't choice A be correct as well because the size of the gas molecules would decrease the volume of the container and so make PV less than nRT?

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
