Question
A carnot engine takes 3 × 106 cal of heat from a reservoir at 627oC, and gives it to a sink at 27oC. The work done by the engine is
Options
A.4.2 × 106
B.8.4 × 106
C.16.8 × 106
D.zero.
Solution
Work done by the engine while taking heat
Q = 3 × 106 cal is W = 2 × 106 × 4.2 = 8.4 × 106 J.
Q = 3 × 106 cal is W = 2 × 106 × 4.2 = 8.4 × 106 J.
