2.0 moles of Ne in a 1.0 dm^3 vessel is mixed with 2.0 moles of He in 1.0 dm^3 vessel by combining the two gases into a 2.0 dm^3 vessel. what is the change in entropy? Assume that the gases are ideal.

(b) Now assume that the gases in part (a) are identical. calculate the change in entropy for the gas system Is this result consistent with part a .

explain why with gibbs paradox?

(This is a famous thermodynamics problem known as the Gibbs paradox.) (5 marks)
