Calculate the work for the isothermal expansion of 2.00 moles of an ideal gas along three different paths. (A) A reversible expansion from 25.0 bar and 4.50 L to 4.50 bar. (B) A single-step expansion against a constant external pressure of 4.50 bar. (C) A two-step expansion consisting initially of an expansion against a constant external pressure of 11.0 bar until Pinternal = Pexternal, followed by an expansion against a constant external pressure of 4.50 bar until Pinternal = Pexternal. (D) Explain the differences in your answers and what these differences mean.
