isothermal
An ideal gas undergoes isothermal expansion from (pi, Vi) to (pf, Vf ). Under what conditions would the work be (i) a maximum? (ii) a minimum? Write the expressions for maximum and minimum work done for this process and explain your reasoning. How would the answer differ if the gas was undergoing isothermal compression instead of expansion?
