of air at 300 K and 150 kPa. It's now heated in a two- Q: A piston cylinder contains 1.5 step processes: first by a constant volume process to 1000 K second a constant pressure process to 1500 K. find the heat transfer for this processes.

5. A piston/cylinder contains air at 600 kPa, 290 K and a volume of 0.01 m3A constant- pressure process gives 54 kJ of work out. Find the final volume, the temperature of the air, and the heat transfer.

Refrigerant R134a in piston cylinder assembly, 200 kPa in initial state pressure and in the form of saturated vapor. It is then reversed and The final pressure is 1000 kPa by being compressed in the adiabatic state change. a) Find the final temperature (°C). b) Find the work done (kj/kg). Note: The changes in kinetic and potential energies will be neglected.

A rigid insulated tank is separated into two rooms by a stiff plate. Room A of 0.5 m3 contains air at 250 Kpa, 300 K and room B is 1 m3 has air at 150 Kpa, 1000K. the plate is removed and the air comes to a uniform state without any heat transferred. find the final temp and pressure of the room.

THERMODYNAMICS A certain gas expand from 7ft3 to 23ft3 while the pressure remains constant at 17.5psia. Find the work nonflow in the system in BTU.

find the work posses for a carbon dioxide gas at 1958.76 C in kj/kg. use W=mRT

Please be very detailed

A 250 L rigid tank contains methane at 500 K, 1500 kPa. It is now cooled down to 300 K. Find the mass of methane and the heat transfer.

(b) Steam at 140 bar has an enthalpy of 3001.9 kJ/kg, find the temperature, specific volume and the internal energy.
