(P-P0/P100-P0)=(x-x0/x100-x0)=(T-T0/T100-T0) (32.45-27.50/37.50-27.50)=(T-O/100-0) T=49.5° C

Q. The pressure of a gas filled in the bulb of a constant volume gas thermometer at temperatures $0^{\circ} C$ and $10 0^{\circ} C$ are $27.50 c m$ and $37.50 c m$ of $H g$ respectively. At an unknown temperature the pressure is $32.45 c m$ of $H g$ . Unknown temperature is

$3 0^{\circ} C$

$3 9^{\circ} C$

$49. 5^{\circ} C$

$29. 6^{\circ} C$

$\frac{P - P _{0}}{P _{100} - P _{0}} = \frac{x - x _{0}}{x _{100} - x _{0}} = \frac{T - T _{0}}{T _{100} - T _{0}}$
$\frac{32.45 - 27.50}{37.50 - 27.50} = \frac{T - O}{100 - 0}$
$T = 49. 5^{\circ} C$
