Homework Statement
Two moles of an ideal gas undergo a reversible isothermal expansion from 3.34E-2 m^3 to 4.80E-2 m^3 at a temperature of 25.7C
What is the change in entropy (ΔS) of the gas?
Homework Equations
ΔS = Q/T
The Attempt at a Solution
first I think I need to calculate the work done by the gas.
and then Q = ΔEint - W
but I am confused.. because this formula requires pressure. and the pressure is not given.
pls.. help me..
thanks in advance..
