Calculate DeltaU and DeltaH when 10dm^(3...

Calculate `DeltaU and DeltaH` when `10dm^(3)` of helium at NTP is heated in a cylinder to `100^(@)C`, assuming the the gas behaves ideally. `(C_(V)=3//2R)`

Text Solution

Verified by Experts

The correct Answer is:
`DeltaU=556.74J`
`DeltaH=927.9J`
`DeltaU=n*C_(V)*DeltaT and DeltaH=n*C_P*DeltaT`
`=(10)/(22.4)xx(3)/(2)xx8.314xx100=556.74J`
`=(10)/(22.4)xx(5)/(2)xx8.314xx100`
`=927.9J`
