A new flourocarbon of molar mass 102 g `mol^(-1)` was placed in an electricity heated vessel. Whwn the pressure was 650 torr, the liquid boiled at `77^(@)` C. After the boiling point had been reached , it was found that a current of 0.25 A from a 12.0 volt supply passed for 600 sec vaporises 1.8g of the sample. The molar enthalpy and enternal energy of vaporisation of new flourocarbon will be :
