1. Three kilograms of neon in a constant volume system. The neon is initially at 550 kPa and 350 K. Its pressure is increased to 2000 kPa by a paddle work with 210 kJ of heat added. Find (a) the final temperature, (b) the change in internal energy, (c) the change in enthalpy, (d) the nonflow work.  2. An ideal gas with Cv = 1.62 kJ/kg-K and R = 273J/kg-K expands from 0.15 m3 and 27oC to 0.35 m3 during an isobaric process with p = 150kPa. Consider the process reversible nonflow, determine (a) the heat, (b) the change in internal energy, © the work nonflow, (d) the change in entropy.  3. A perfect gas with R = 320 J/kg-K and Cp = 1.6 kJ/kg-K. If 150 kJ of heat is added to 5 kg of this gas at constant pressure when t1 = 35 deg.C, find (a) the work nonflow, (b) U, (c)S. 4. Three kilograms of an ideal gas with R = 204 J/kg-K and k = 1.667 have 316 kJ of  heat added during an isobaric process. The initial temperature is 38oC. Determine (a) Wnf, (b) U, (c) S. 5. During an isothermal…

Hi, I need help with this problem. Please provide a readable solution for it. Thanks a lot.

3kg of Co2 expanded in a stationary piston cylinder through a polytropic process from 30 degree Celsius and 250 kpa to 100kPa pressure. If the polytropic exponent, n = 1.45, find the total work, total heat transferred, total kinetic energy change and internal energy change

Please state the assumptions and tables.

A fluid is heated reversibly at a constant pressure of 1.05 bar until it has a specific volume of 0.1 m'/kg. It is then compressed reversibly according to a law pu = constant to a pressure of 4.2 bar, then allowed to expand reversibly according to a law pel.- constant, and is finally heated at constant volume back to the initial conditions. The work done in the constant pressure process is -515 N m, and the mass of fluid present is 0.2 kg. Calculate the net work of the cycle and sketch the cycle on a p-v diagram.
