1. Calculate the following values:

(a) Calculate the work done (in joules) when 0:250 L of gas expands to a volume of 0:850 L against an external pressure of 850:0 torr.

(b) Calculate the work done (in joules) when 0:250 L of gas expands to a volume of 0:482 L against an external pressure of 1500:0 torr, followed by expansion to a volume of 0:850 L against an external
pressure of 850:0 torr.

(c) Which of the single or multiple step expansions involves the largest transfer of heat? Why?
