A cornot engine has the same efficiency ...

A cornot engine has the same efficiency between (i) 100 K and 500 K and (ii) T and 900 K. Find T.

A

`200 K`

B

`180 K`

C

`200 K`

D

`230 K`

Text Solution

Verified by Experts

The correct Answer is:
B
Efficiency is `eta = 1 - T_2/ T_1`. That is, `eta = 1 - 100/ 500 = 1 - T/900 rArr 100 /500 rArr T = 180K`
