Question

When a thermometer is taken from the melting ice to a warm liquid, the mercury level rises to of the distance between the lower and the upper fixed oints. The temperature of liquid in K is

• A. 217.15
• B. 313.15
• C. 220
• D. 330

Answer 1

Answer: (B)

313.15

Answer 2

Here, temperature of liquid $= \frac{2}{5}$ of distance between lower and upper fixed point$= \frac{2}{5} \times 100 = 40{^\circ}C$

On Kelvin scale, $T_{K} = 273.15 + 40 = 313.15K$
