Consider a transformation from point A to B in a two-step process. First, the pressure is lowered from 15 MPa at point A to a pressure of 3 MPa, while keeping the volume at 2.3 L by cooling the system. The state reached is labeled C. Then the system is heated at a constant pressure to reach a volume of 6.0 L in the state B. (Assume the system consists of a monatomic ideal gas.)

need part B

Part B)

Find the amount of heat exchanged (in J) by the system when it goes from A to B on the ACB path.

A mole of a monatomic ideal gas is taken from an initial pressure p and volume V to a final pressure 3p and volume 3V by two different processes: (I) It expands isothermally until its volume is tripled, and then its pressure is increased at constant volume to the final pressure. (II) It is compressed isothermally until its pressure is tripled, and then its volume is increased at constant pressure to the final volume. Show the path of each process...

This is a problem involving an engine with a three thermodynamic process cycle. We have an monatomic ideal gas in a cylinder that can expand and contract. The cylinder can be connected to a hot thermal reservoir at temperature, TH, and also can be connected to a cold reservoir at temperature, TC. We start out at temperture, TH, with Pressure P1 and volume V1. a)Keeping the cylinder connected to the hot reservoir we expand isothermaly to a new volume V2....

a) Calculate delta S(system) for the reversible heating of 1 mol of ethane from 298K to 1500 K at constant pressure. Use Cp = 5.351 + 177.669x10-3 T – 687.01x10-7 T ^2 + 8.514x10-9 T ^3 (J/mol K). Consider the reversible Carnot cycle discussed in class with 1 mol of an ideal gas with Cv=3/2R as the working substance.

Chapter 5- Gases 24. As weather balloons rise from the earth's surface, the pressure of th atmosphere becomes less, tending to cause the volume of the balloons to exand. However, the temperature is much lower in the upper atmosphere that at sea level. Would this temperature effect tend to make such a balloon expand or contract? Weather balloons do, in fact, expand as they rise. What does this tell you? 37. Freon-12 (CF2Cl2) is commonly used as the refrigerant in...

A fuel gas consists of 75% butane (C4H10), 10% propane (C3H8) and 15% butene (C4H8) by volume. It is to be fed to the combustion chamber in 10% excess air at 25ºC, where it is completely burnt to carbon dioxide and water. The flue gases produced are to be used to generate 5 bar steam from water at 90ºC. (a) Write balanced equations for the combustion of each component of the fuel gas. (b) Explain the need for excess air....
