Estimate the specific volume of water at temperatures ? = 600 C for the following pressures: P = 40 bar using : (a) Van de Waals constitutive eq. (b) Redlich Kwong constitutive eq. (c) Thermodynamic tables.

Need a b c

Please show complete solving and claer explanation. Thank you!   In the reversible isothermal expansion of an ideal gas at 300K from 1 to 10 L, where the gas has an initial pressure of 20.27 bar calculate: (a) delta S for the gas (b) delta S for all the systems involved in the expansion

5. If a gas of volume 6000 cm³ and at pressure of 100 kPa is compressed quasi-statically according to PV² = constant until the volume becomes 2000 cm³, determine the final pressure and the work transfer.
