- Find J for the normal compression of 2 mol of ideal gas in the piston at a temperature of 311 K, from 1 bar to 10 bar. Gas constant R=8.314 J/(mol K).arrow_forward3.23 3.24 d 3.25. Gas at constant T and P is contained in a supply line connected through a valve to closed tank containing the same gas at a lower pressure. The valve is opened to allow flow of gas into the tank, and then is shut again. (a) Develop a general equation relating n1 and n2, the moles (or mass) of gas in the tank at the beginning and end of the process, to the properties U1 and U2, the internal energy of the gas in the tank at the beginning and end of the process, and H', the enthalpy of the gas in the supply line, and to Q, the heat transferred to the material in the tank during the process. (b) Reduce the general equation to its simplest form for the special case of an ideal gas with constant heat capacities. (c) Further reduce the equation of (b) for the case of n1 = 0. (d) Further reduce the equation of (c) for the case in which, in addition, Q = 0. (e) Treating nitrogen as an ideal gas for which Cp equation to the case in which a steady supply of nitrogen at 25°C and…arrow_forward1) Given a vessel with V = 0.4 m3 filled with m = 2 of H2O at P = 600 kPa, find • the volume and mass of liquid, and • the volume and mass of vapor.arrow_forward

If the derivative ∂u/∂x appears in an equation, what does this imply about variable u?arrow_forward
- Show that for perfect gas, Cp,m - Cv,m =Rarrow_forwardA mass of 12 kg of Oxygen occupying 3 m3 is heated from 25°C at a constant volume. Take gas constant is 0.297 kJ/kgK, then its initial pressure would be approximately 0.78 bar. Select one: O True O Falsearrow_forward200 J of energy is transferred to a system consisting of 2.0 moles of an ideal gas. If the volume of this gas stays at a constant 2.6 L, calculate the change in internal energy of the gas. Jarrow_forward
- A chamber is divided equally into two parts by a membrane. One side contains Hydrogen, H2, at a pressure of 200 kPa and temperature of 300 K, and the other side is evacuated (a perfect vacuum). The total chamber volume is 0.005 m3. At time t = 0, the membrane ruptures and the hydrogen expands freely into the evacuated side. The chamber can be considered adiabatic (i.e. perfectly insulated). Find the final values of the temperature and pressure.arrow_forwardplease find T2 and V2 for a mole of freon given such that enthalpy is conserved and P2 = 10^5 Pa, use the van der waals model. See attached imagearrow_forwardIn Figure , the radial distribution function P(r) for the 2s state of hydrogen has two maxima. Find the values of r (in terms of a0) where these maxima occur.arrow_forward
