2. 10 points Consider a thermally isolated system consisting of two volumes of an ideal gas separated by a thermally conducting movable partition, which is initially fixed. Initially, the temperatures, pressures, and volumes of the two parts are P, V, T and 3P, 2V, and T respectively (see figure below). The partition is now allowed to move without gases mixing, until the equilibrium is reached. a) What is the change of the internal energy of the system after the equilibrium...

Asking for Q3,4,5,6.
Mixing Gases Consider two containers, . Both have volume 0.1 m3, and pressure 106 pa One contains monatomic (3 degrees of freedom) He at T 128 K and One contains diatomic (5 degrees of freedom) N2 at T- 258 K. A valve is opened allowing these two gases to mix. They are kept thermally isolated from the outside You can treat them as i deal gases. 1) What is the change in internal energy under this process?...

2 a) An ideal gas with a Cv of 1.5R independent of temperature is initially contained in a volume of 0.05 L at a pressure of 10 atm and an initial temperature of 1200°C. The volume is then increased to 0.50 L. What will be the final pressure and temperature of the gas if the total amount of gas is unchanged, and the gas undergoes reversible adiabatic expansion? How much work will be produced? Calculate the change in entropy of...

B. Two distinguishable monatomic ideal gases A and B are held in a volume V by a movable partition of zero weight and volume. The relative proportions of A and B are arbitrary as the system is in equilibrium (i.e., the pressure P and temperature T are uniform throughout the system). Let N = N , +N be the total number of molecules and let x be the fraction of speed or (NB = XN). (a) Calculate the change in...

A rectangular box is divided into three spaces that are separated by two barriers. The first space constitutes half the volume of the box, while the second and third spaces each constitute one quarter of the volume. Initially, 2 moles of oxygen are placed in the first space, 1 mole of nitrogen is in the second space, and 1 mole of argon is placed in the final space. After the system is setup, the partitions are removed and the gases...

A composite system consists of two chambers connected by a short pipe with an insulated valve in it. Each chamber has a volume of 0.5 m and the composite system is insulated so it is thermally isolated from the surroundings. Initially the valve is closed and one cham- ber contains 0.5 moles of N2 gas at 400 K while the other contains 0.5 moles of Br2 gas at 800 K. The valve is opened and the gases are allowed to...

Two rigid tanks are connected by a valve. Initially, one tank contains 10 mº of helium (He) gas at 220 kPa, 40°C? The other tank initially contains 4.0 R of neon (Ne) gas at 150 kPa, sot. Now the valve is opened, allowing the two gases to mix with each other. Heat transfer occurs during the mixing process. The final equilibrium temperature is 44'C. The specific heats of monatomic gases are independent of temperature. Determine: (a) the final volume of...
