B) 1.6
C) 1.2
D) 4.8
Correct Answer: C
Solution :
Efficiency of a Carnot engine is given by \[\eta =1-\frac{{{T}_{2}}}{{{T}_{1}}}\]\[\frac{W}{Q}=1-\frac{{{T}_{2}}}{{{T}_{1}}}\Rightarrow \frac{W}{6}=1-\frac{(273+127)}{(273+1=227)}\] \[\Rightarrow \]\[W=1.2\,kcal\]You need to login to perform this action.
