ideal gas law?

Question

Which of the following four statments are true for real gases and the corrections that must be made to the Ideal Gas Law?

a) the constant b in van der waals equation corrects for volume of real particles

b) the constant a in van der waals equation corrects for attractions between particles

c) the attraction of particles increases observed pressure

d) particles have finite volume

note may be more than one answer

Answer 1

b) is the best answer. Check out this page:

It goes through the entire development of the ideal gas laws, and show's van der Waal's equation and talks about the corrections...

Answer 2

ideal gas regulation basically works on gasses with specific characteristics. the ideal gas regulation assumes that the molecules do no longer attrat one yet another, have not any mass, etc. this does not carry genuine below specific circumstances, like at temperatures on the edge of absolute 0 (the gas molecules show charm at such low temperatures)
