Consider two fixed-volume systems A and B, in thermal equilibrium and that can exchange two different types of particles (say type 1 and type 2). Given that equilibrium is a state of highest multiplicity, show that in order for A and B to be in equilibrium, then systems A and B must have equal chemical potential in each type of particles that they can exchange.
The boiler in an apartment building uses propane (C3H8) to heat water that circulates throughout the building as steam. 1.00 m'/s of propane gas at 25°C and 1 atm is combusted with 10% excess air at 25°C and 1 atm. After all of the propane is combusted, the product gas contains a 10.0:1 molar ratio of CO2 to CO and leaves the boiler at 25°C. Heat from the boiler is transferred to a pure water stream at 50°C and 1.0 bar, which is converted into saturated steam at 20 bar, with no heat lost to the surroundings in the process.

The gas A(g) (1 mole) undergoes a two-step process one after another as described below :i) The gas is expanded at 25°C and from 1 bar pressure against a constant pressure of 0.2 bar and the final volume of the gas is the twice the initial volume.ii) The gas is cooled down to -25°C at constant volume.Cv,m = 3/2 RCalculate ΔU, ΔH, q and w for the each step and for the entire process
A 0.2m3 rigid tank initially contains pure oxygen gas (02) at 20°C and 1000 kPa. The tank containing the oxygen is put on a scale to measure its mass. The initial mass is recorded as 110.4 kg. Nitrogen gas is injected isothermally into the tank until the scale reads 121.0 kg. The molar mass of oxygen is 32kg/kmol and the molar mass of nitrogen is 28 kg/kmol. Assuming that the gases behave ideally, answer the following questions: a) What is the mass of the empty tank? b) What is the composition of the final mixture on a mole basis? c) What is the final pressure of the tank? d) The critical temperature and pressure of oxygen are 154.6K and 49.8atm. Based on these properties, comment on the appropriateness of using the ideal gas law in part a)

Qui Air in a closed piston-cylinder arrangement is expanded from the initial pressure of 8.3 bar and initial volume of O.029 m to the final state of p2 2.2 bar. A polytropic relation of pV13 = constant was followed between pressure and volume for the process. The specific internal energy at the initial and final states are 156.5 and 101.5 kJ/kg, respectively. The mass of the air is 0.28 kg. Neglecting the effect of kinetic and potential energy, determine the heat transfer, inkJ.
