A Carnot engine has the same efficiency between `800 K` to `500 K` and `x K to 600 K`. The value of `x` isA. 100 KB. 960 KC. 846 KD. 754 K%

Answer» Correct Answer - B
As, `eta=1-(T_(2))/(T_(1))=1-(500)/(800)=1-(600)/(x)`
`therefore(3)/(8)=1-(600)/(x)rArr(600)/(x)=1-(3)/(8)=(5)/(8)`
5x=4800
`x=(4800)/(5)=960 K`
