Question

Problem 6.2 isothermal and free expansion of an ideal gas

Answer 1

Answer:

Explanation:

In a free expansion, Internal energy of gas decreases.

Answer 2

In other words, in isothermal process ∆T = 0. Free expansion of a gas occurs when it is subjected to expansion in a vacuum (pex=0). During free expansion of an ideal gas, the work done is 0 be it a reversible or irreversible process. ... Isothermal reversible change: q = -w = nRTln (Vf/Vi) = 2.303 nRT log (Vf/Vi)
