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

Explanation

`T' = V/ V-V' xx T_0'`
`T_0 =273K`
`V = 1800 cc`
`V' =200cc`
`T' =1800/1600 xx 273`
`307.125~~307`
