The pressure of the gas in a constant volume gas thermometer are 80 cm, 90 cm and 100 cm of mercury at the ice point, the steam point and in a heated wax bath respectively. Find the temperature of the wax bath.

Explanation

Given
`P_ ice point = P_0+80cm Hg`
`P_ steam point= P_100 =90 cm Hg`
`P_0 = 100cm`
`T = (P- P_0)/ (P_100-P_0) xx 100^0 C`
`= 80-100/90-100 xx 100`
`=20/10 xx 100 = 200^0 C`
