A piston cylinder contains air at 600 kPa, 290 K and a volume of 0.01m^3. A constant pressure process gives 54 kJ of work out. Find the mass in the .cylinder in kg 1.38 O 0.138 O 0.072 O 720 O

A piston cylinder device contains 6 kg hydrogen gas. Heat is transferred to the hydrogen as the temperature increases by 46.07 F. What is the boundary work done during this process kW.

i need the answer quickly

A cylinder fitted with a piston has a volume of 0.1 m'and contains a 0.8 kg of steam at 0,.4 MPa. Heat is trausferred to the steam umntil the temperature is 250°C, while the pressure remmains constant. (1) vi (specific volume) in m'kg = (2) v: (specific volume) in m'kg = (3) xi (quality) = . (4) us (specific internal energy) in k/kg (5) uz (specific internal energy) in kJ/kg =. (6) Xx: (quality)= (7) Phase description at imitial state is.
