Consider a Carnot's cycle operating between `T_(1)`=500 K and `T_(2)` = 300 K producing 1 kJ of mechanical work per cycle. Find the heat transferred to the engine by the reservoirs.

Options

A. 2000J
B. 2500J
C. 1500J
D. 1000J

Answer

B

Explanation

`eta =1 -(T_(2))/(T_(1))=1-(300)/(500)=(2)/(5)`
` eta =(W )/(Q) Q =(W) /( eta) =(1000J)/(2//5)`
`Q=2500J`
