A sealed container of volume 7 m³ has two compartments with a barrier in between them. In one compartment, there is O2 at an initial pressure of 3 atm, initial temperature of 540 K, and volume 3 m³. In the other compartment, there is CO2 at an initial pressure of 5 atm, initial temperature of 430 K, and volume 4 m³. The barrier in the middle is punctured and the two gases mix together. What is the final pressure and temperature of the two gases and what is the change in entropy of the universe after the gases combine

An ideal gas in a sealed container has an initial volume of 2.55 L. At constant pressure, it is cooled to 20.00 °C where its final volume is 1.75 L. What was the initial temperature? A sample of xenon gas occupies a volume of 9.47 L at 403 K. If the pressure remains constant, at what temperature will this same xenon gas sample have a volume of 6.29 L?

In osmosis, when will there be changes in volume of the two compartments separated by a selectively permeable membrane? A. When particles in solution are prevented from crossing the membrane (nonpenetrating solutes). B. When the water concentrations on both sides of the compartments are the same. C. When particles in solution can diffuse across the membrane along with water. D. When the solutes concentration on both sides of the compartments are the same.

The volume of 1 kg of helium in a piston-cylinder device is initially 7 m3 . Now helium is compressed to 3 m3 while its pressure is maintained constant at 150 kPa. Determine the initial and final temperatures of helium as well as the work required to compress it, in kJ. You may assume deal gas behavior.
