- C$I = II = III$
- DData Insufficient
✓
Answer
Correct option: B.
$I < II < III$
b
$\Delta \text{T}=\frac{1000\times {{\text{K}}_{\text{f}}}\times \text{w}}{\text{M}\times \text{W}}$ $ = \frac{{1000 \times 4.9 \times 2}}{{122 \times 25}} = 3.213$
$\Delta \text{T}=\frac{1000\times {{\text{K}}_{\text{f}}}\times \text{w}}{\text{M}\times \text{W}}$ $ = \frac{{1000 \times 4.9 \times 2}}{{122 \times 25}} = 3.213$
$\mathrm{i}=\frac{\Delta \mathrm{T}_{\mathrm{erg}}}{\Delta \mathrm{T}_{\mathrm{cal}}}=1-\alpha+\frac{\alpha}{\mathrm{n}}$
$\frac{1.62}{3.213}=1-\alpha+\frac{\alpha}{2}$
$\alpha=0.992$ or $99.2 \%$
