Question

In a Callcnder's compensated constant pressure air thermometer, the volume of the bulb is 1800 cc. When the bulb is kept immersed in a vessel, 200 cc of mercury has to be poured out. Calculate the temperature of the vessel.

Answer 1

$T^{\prime }=\frac{V}{V-V^{\prime }}\times T_0$

$T_0=273K$

V = 1800 cc

V' = 200 cc

$T^{\prime }=\frac{1800}{1600}\times 273$

= 307.125 $\approx$ 307
