An ideal gas with MW of 29 g/mol, cp = 1.044 kJ/kgK and c₁ = 0.745 kJ/kgK contained in a cylinder-piston assembly initially has a pressure of 175 kPa, a temperature of 22°C, and a volume of 0.30 m³. It is heated slowly at constant volume (process 1-2) until the pressure is doubled. It is then expanded slowly at constant pressure (process 2-3) until the volume is doubled. Draw a figure of the system and the PV diagram showing each state and the path each process takes. Determine the total work done by the system and total heat added (J) in the combined process.

V. W. Th To %3D Room temperature T = 293 K V V. Vp The gas volume changes from Vp to Va at constant temperature T. The cartoon on the right shows a piston of gas undergoing this compression while submerged in a container of room temperature water, which acts as a reservoir. The initial state of this process is a piston containing 2 moles of a monatomic gas at Tc = 293 K (room temperature water) and volume V = a 1.0 m. The gas is compressed until V, = 0.2 m. During the compression, the heat bath of room temperature water maintains the temperature of the gas at T 293 K. Calculate the work done in joules by the gas during this process. Do not include units in your answer. Be careful to use the standard sign convention for work done by the gas. Write your numerical answer in normal form as described above in the instructions to this worksheet.

A piston-cylinder device contains an ideal gas of nitrogen. At the initial state, the volume is V₁ = 1.00 m³, the pressure is p₁= 400.00 kPa, the temperature is T₁=300.00 K. An electric heater within the device is turned on for a time of At = 5.00 min. The current is I = 3.00 A, and the source voltage is V = 120.00 V. During the heating process, the gas expands, and a heat loss of Qout = 2.80 kJ occurs. The gas constant is R = 0.297 kPa m³/(kg-K), and the room temperature specific heat at constant pressure is cp =1.039 kJ/(kg-K). Calculate the final state temperature, T2. (K) Gas

Properties of Pure Substancies What is the specific internal energy of water at 50 kPa and 20°C?

pls correct the given this is my last attempt

During processing in a steel mill, a 375kg steel casting at 800 degrees  is quenched by plunging it into a 500-gal oil bath, which is initially 75 degrees . After the casting cools and the oil bath warms , what is the final tempertature of the two? The weight per unit volume of the oil is 7.5 lb/gal.

I need a clear and fast answer within 20 minutes. Thank you

A cylindrical vessel with a diameter of 8 inches and 5 feet long contained acetylene at 300 psi gauge and 82°F. After some amount of acetylene was used, the pressure was reduced to 190 psi gauge and the temperature was 74°F. The gas constant of acetylene is 59.35 ft-lb:/lbm-°R. Determine the following: 1. What is the initial mass in Ibm of the acetylene inside the vessel? 2. What proportion in percentage of acetylene was used? 3. What volume in ft would the used acetylene occupy at 30 psig and 80°F?

need the correct ans

.A kilogram of Argon gas( MW= 40 kg/kmol, k=5/3) is in a piston cylinder set-up. Initially, it has pressure of 30kPa and volume of 0.2m3 and expanded to 20 kPa due to heat transfer. If the process is said to be isovolumic, find initial and final temperatures.
