- 3.2. Heat and Work 0.2 kg of argon (mon-atomic ideal gas, R = 0.208 kJ/kgK ), initially at 250K, are confined in an isochoric system of 0.15 m^3 volume, and 2.5 kg of xenon (mon-atomic ideal gas, R = 0.063 kJ/kgK ), initially at 420K, are confined in an isobaric piston-cylinder system at 1.8 bar. Both systems are brought into thermal contact and equilibrate their temperatures with no heat loss to the outside. What is the final temperatures, pressures and volumes of both gases, the work done by both systems, and the amount of heat transferred between the two systems and the total generation of entropy? (Sgen= ∫ Sgen dt ) and s=Cv =3/2R, Cp =5/2RIn what four states does matter exist? Cite examples of each.Suppose there are two identical gas cylinders. One contains the monatomic gas krypton (Kr), and the other contains an equal mass of the monatomic gas radon (Rn). The pressures in the cylinders are the same, but the temperatures are different. Determine the ratio KEr /KERN of the average kinetic energy of an atom of krypton to the average kinetic energy of an atom of radon. The answer should be a value.
- please be clearConsidering an alloy of the two soluble components A and B described by aphase diagram Figure P2.31, determine the masses of the alloy that are in theliquid and solid phases at a given temperature if the total mass of the alloy is100 g, component B represents 40% of the alloy, 20% of the liquid is component B, and 50% of solid is component B.6. Moist steam is contained in a sturdy sealed container (mass and volume unknown). If heating continues, choose all of the following possible and briefly explain why. (a) The mass of the vapor gradually increases. (b) The mass of the liquid gradually increases. (c) The ratio of liquid and gas does not change.

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.
