An ideal gas with molecular weight of 6.5 kg/kgmol is compressed in a reversible manner from 690 kPa and 277 K to a final specific volume of 0.47m3/kg accordning to p=561 + 200v+ 100v^2, where p is the pressure in kPa and v is the specific volume in m3/kg. The specific heat at constant volume is 0.837 kJ/kg-K. Determine a) the work; b) the heat; c) the final temperature; d) the initial specific volume
