An insulated contains 1mole of a liquid, molar volume `100mL` at 1bar. When liquid is steeply passed to `100`bar, volume decreases to `99mL`. Find `DeltaH` and `DeltaU` for the process.

Explanation

From the first law of thermodynamics
`DeltaU = q +w`
`DeltaU = q+ P DeltaV = 0 +{-100(99-100)}`
`= 100 "bar" mL`
`DeltaH = DeltaU +(P_(2)V_(2)-P_(1)V_(1)) = 100 +(100 xx 99 -1xx100)`
`=9900 "bar" mL`
