The pressure of the gas in a constant volume gas thermometer is $\displaystyle 100$ cm of mercury when placed in melting ice at $\displaystyle 1$ atm. When the bulb is placed in a liquid, the pressure becomes $\displaystyle 180$ cm of mercury. Temperature of the liquid is :
(Given $\displaystyle 0^{\circ} \mathrm{C}=273 \mathrm{~K}$ )
Official answer
(4)
$\displaystyle 491$ K
