MCQ
Efficiency of Carnot engine is $100\%$ if
- A${T_2} = 273\,\,K$
- ✓${T_2} = 0\,\,K$
- C${T_1} = 273\,\,K$
- D${T_1} = 0\,\,K$
✓
Answer
Correct option: B.
${T_2} = 0\,\,K$
b
(b) $\eta = 1 - \frac{{{T_2}}}{{{T_1}}}$ for $100\%$ efficiency $\eta = 1$ which gives $T_2 = 0\, K.$
(b) $\eta = 1 - \frac{{{T_2}}}{{{T_1}}}$ for $100\%$ efficiency $\eta = 1$ which gives $T_2 = 0\, K.$
