Two noble gases (Ne and He) are injected into the chambers of an insulated container. Each container has the same number of particles, 1 mol, but the volume when He(g) is 1/3 than the container with Ne(g). It is also known that initially, the Helium has twice the internal energy as Neon. Assume He(g) is at 10 atm of pressure with a volume of 0.5 liters.
Estimate the increase in entropy for the mixing of the two 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...

Problem 5: This problem deals with gases used for a He-Ne laser. Consider the Neon transition at 632.8 nm. The upper level of the transition (with respect to ground level of Neon) coincides with a 2s level of Helium that has the energy of 20 eV with respect to the ground level of Helium. The gases are kept at room temperature (300K). We consider only three different energy levels of Neon: ground level, lower level of the laser transition, and...

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...
