One mole of a monatomic ideal gas is transformed from 0.00°C and 2.00 atm to
-40.0°C and 0.400 atm. Show that this is NOT an adiabatic reversible expansion and
calculate ΔS for the change. (Hint: you will need to consider a reversible path that
includes a constant pressure step and a constant temperature step.)
The Attempt at a Solution
For adiabatic reversible expansion, q=0, so i have to show that q= a number.
Found Vi= 11.2L and Vf=47.8L via ideal gas law
