One mole of an ideal gas undergoes a reversible isothermal expansion from a volume of 1 L to a volume of 2 L. The change in entropy of the gas in terms of the universal gas constant R is?
Final Answer is R ln(2), but I need to know how to calculate this
Homework Answers
or, making use of the equation of state and the fact
that 
for an isothermal
process,
so as v2 =2v1
and N =1 mol3:
therefore:
ENTROPY = R ln(2)
Here,
v2 =2 l, v1 = 1 L , number of mole is one
so answer will be
Delta S = R ln 2
