When sample of hydrogen is immersed in a mixture of ice and water, it occupies an exact volume of 69.37 cc at 1 atm. At the same pressure, if the gas is immersed in boiling benzene, then its volume expands to 89.71 cc. what is the boiling point of benzene ?

Text Solution

Verified by Experts

As the pressure and amount of the `H_(2)` gas are fixed, according to Charles's law `V_(1)//V_(2)=T_(1)//T_(2)`
Temperature of the mixture of ice and water
`=0^(@)C=273K`. Given `V_(1)=69.37c c and V_(2)=89.71 `cc.
`therefore T_(2)=T_(1)xx(V_(2))/(V_(1))=273xx(89.71)/(69.37)=353.05K`
`therefore` The boilng point o benzene`=(353.05-273)^(@)C`
`=80.05^(@)C`
