    Q:

    		 The efficiency of a heat engine is calculated by the formula Efficiency = 1 - (T1/T2) where T1 is the cold reservoir and T2 is the hot reservoir. Which of the following will maximize efficiency of the system?
    		 

    A

    		 In the cold reservoir, increasing pressure while keeping volume constant

    B

    		 In the hot reservoir, decreasing pressure proportionally to a volume increase.

    C

    		 In the cold reservoir, decreasing pressure while keeping volume constant

    D

    		 Decreasing pressure in both the hot and cold reservoirs by the same proportions
