An ideal gas heat engine operates in carnot cycle between 227^ C and 127^ C . It absorbs 6 10^4 cal of heat at higher temperature. Amount of heat converted into work, is:
Options
- A4.8 10^4 cals
- B6 10^4 cals
- C2.4 10^4 cals
- D1.2 10^4 cals
Correct answer
D. 1.2 10^4 cals
Step-by-step solution
For a carnot engine efficiency aligned e & =1- T₂ T₁ & =1- 127+273 227+273 & =1- 400 500 = 1 5 aligned Now, e= Work Output Heat Output = W 6 10^4 aligned W & =e 6 10^4 & = 1 5 6 10^4 & =1.2 10^4 cal . aligned
