A cylinder is fitted with a freely movable piston of area 1.20e-2m^2 and negligible mass. The cylinder below the piston is filled with a gas. At state 1 the gas has volume 1.50e-3m^3, pressure 1.02e5Pa, and the cylinder is in contact with a water bath at a temperature of 0.0C. The gas is then taken through the following four step process. - A 2.50kg metal block is placed on top of the piston, compressing the gas to state 2, with the gas still at 0.0 C. - The cylinder is then brought in contact with a boiling water bath, raising the gas temperature to 100C at state 3. - The metal block is removed and the gas expands to state 4 still at 100C. - Finally, the cylinder is again placed in contact with the water bath at 0C, returning the system to state 1. a) Determine the pressure of the gas in state 2. b) Determine the volume of the gas in state 2. C) Determine the volume of the gas in state 4. Answer all parts, ABC

The relatice humidity in a room of 2mx3mx6m is 80% at 18 °C. A cylinder with 2dm^2 area is placed in the middle of the room with 4 liter water inside (density=1gcm^-3) The room is closed. We increase the temperature of the room to 25 °C and wait for equilibrium to set in. Calculate the height of the remaining water column in the cylinder. The vapor pressure of water at 18 °C is 2065 Pa and the enthalpy of vaporization is 44kJ/mol within the investigated temperature range.

Water vapor at the throttling valve inlet in a piping circuit at 4MPa pressure at 300 °C is at the temperature. Since the pressure is 3MPa at the outlet of the throttling valve, the outlet of the fluidIndicate its temperature and which phase it is in by drawing it in the P-h diagram.
A rigid tank of volume 0.6 m3 contains saturated R-134a vapor at 24°C. The contents are cooled until the temperature is O°c. How much heat is removed? Show the process on a P-v diagram.
Saturated water mixture in a piston cylinder arrangement is initially at 200 oC with a qualityof 50%.

A 10-ft3 vessel of hydrogen at a pressure of 305 psia is vigorously stirred by paddles until the pressure becomes 400 psia. Determine ΔU, ΔH, and paddle work (Wp). Assume the vessel is fully insulated
A 0.5-m3 vessel contains 10 kg of refrigerant-134a at -20 °C. Determine (a) the pressure, (b) the total internal energy, and (c) the volume occupied by the liquid phase.
What is the difference between specific internal energy and specific enthalpy in first law of Thermodyanamics and when should i use which? From what i understand so far for constant pressure process, we use q-w=h2-h1 and constant volume process, we use q-w = u2-u1. But this isnt the answer i am looking for.
