Correct or Incorrect Statement?

1) The second law of thermodynamic is based on the thermal equilibrium principle. 2) The heat added at constant pressure is greater than that at constant volume. 3) The latent heat of vaporization of water at the critical point is 0.0 kJ. 4) A polytropic process PV" = C having the value of index 'n' as (0.0) refers to isobaric. 5) The zero law of thermodynamic is a mass balance law. 6) The power cycles can have a thermal efficiency of 100%. 7) The C.O.P of the heat pump (in winter) is more than one. 8) The steam cycle efficiency increases with the boiler pressure. 9) The steam cycle efficiency increases with the condenser pressure. 10) The steam cycle efficiency increases with the turbine inlet temperature.
