An amount of an ideal gas undergoes the process shown in the diagram below. Assume that during the entire cycle, the number of moles of the ideal gas stays constant. P B A V (a) What are the signs of Why the gas Q, and AEint for the process CA? Wby the positive vx What is the work done by the gas if the volume is constant? What happens to the pressure? Consider the relationship of pressure, volume, and temperature in the ideal gas law. Does the temperature change? Does the internal energy change? How is the sign of AEint related to the signs of Q and Wby the gas gas vx What is the work done by the gas if the volume is constant? What happens to the pressure? Consider the relationship of pressure, volume, and temperature in the ideal gas law. Does the temperature change? Does the internal energy change? How is the sign of AEint related to the signs of Q positive and Wby the gas zero vx What is the work done by the gas if the volume is constant? What happens to the pressure? Consider the…

Q. what pressure is generated when 500 mol of methane is stored in a Volume of 0.06 m3 at 50 'C ? Base Calculations on each of the following: (a) The ideal_gas state. (B) The R/K equation. (c) SRK where Te= 190.6 K and P = 45.99 bar From Table B.1 (D) PR

(5) Consider a gas that follows the equation of state NRT aN? p = V – bN V2 | 8a This is called van der Waals gas (a,b > 0). For temperatures T > Tc = p(V) is a 27RB monotonic decreasing function. Assume T > Tc and Cy = 3NR/2. Consider an insulated box with volume V, . The box was divided by a wall. One of the compartments had volume Vo at temperature To, filled with van der Waals gas of amount N, and the other was vacuum. The system was in equilibrium. (a) The wall was removed abruptly. The gas expanded and occupied the entire box. This process is called adiabatic free expansion. The temperature in the box is now T, in equilibrium. What is T, – T,? (b) The internal energy of the gas does not change by adiabatic free expansion. Why? (c) Instead of the abrupt removal, the wall was moved through adiabatic and quasi-static process, and the gas expanded to the entire volume of the box. The temperature in the box is now T, in equilibrium. What is T2? (d) Show T, > T2, using the arguments of…
