Question

When a thermometer is taken from the melting ice to a warm liquid, the mercury level rises to (2th/5) of the distance between the lower and the upper fixed points. The temperature of liquid in K is (A) 217.15 (B) 313.15 (C) 220 (D) 330

Here, temperature of liquid =(2/5) of distance between lower and upper fixed points =(2/5)×100=40°C On Kelvin scale, TK=273.15+40=313.15 K

Q. When a thermometer is taken from the melting ice to a warm liquid, the mercury level rises to $\frac{2 ^{t h}}{5}$ of the distance between the lower and the upper fixed points. The temperature of liquid in $K$ is

$217.15$

$313.15$

$220$

$330$

Here, temperature of liquid $= \frac{2}{5}$ of distance between lower and upper fixed points $= \frac{2}{5} \times 100 = 4 0^{\circ} C$
On Kelvin scale, $T_{K} = 273.15 + 40 = 313.15 K$

Q. When a thermometer is taken from the melting ice to a warm liquid, the mercury level rises to 52th​ of the distance between the lower and the upper fixed points. The temperature of liquid in K is

217.15

313.15

220

330
