I need help on this question: This question requires the use of Thermodynamics Property Tables. In addition, for steam, the specific ideal gas constant = 461.5 J/kg K. Q. A closed system is comprised of 10 kg pure water substance initally at a temperature of 400 oC and a pressure of 8.5 MPa (State 1). a) For state 1, show that the system is in the superheated vapour phase.  b) Evaluate the specific volume of the steam in state 1 using the thermodynamic property tables supplied and compare it to the value obtained assuming the steam behaves as an ideal gas. Which value woyld you have most confidence in (give reasons for your choice).
