Given : Delta_("vap")H" at "373K=40.693kJmol^(-1), C_(p)(H_(2)O,l)=75.312JK^(-1)mol^(-1), C_(p)(H_(2)O,g)=33.305JK^(-1)mol^(-1). Pressure over 1000 ml of a liquid is gradually increases from 1 bar to 1001 bar under adiabatic conditions. If the final volume of the liquid is 990 ml, calculate DeltaUandDeltaH of the process, assuming linear variation of volume with pressure. |
| Answer» SOLUTION :`DeltaU=501J,DeltaH=99.5kJ` | |
