Calculate the new pressure occurring when argon at 25 oC and 1.00 bar in a container of volume 0.500 L is compressed to 0.0500 L and cooled to -25 oC. Also, calculate the entropy change for this process by combining the entropy changes from isothermal and isochoric processes that move the system from the same initial point to the same final point in two stages.

Acetone, C3H6O, has a vapor pressure of 0.307 bar at 25 ºC. A sample of 0.100 mol acetone is added to a container that contains 1.00 L of argon gas at 1.00 bar pressure and 25 ºC. The volume of the container is then increased to 4.00 L while maintaining the same temperature. What is the pressure in the container after the expansion? It is supposed to be C but I am not sure why. (A) 0.250 bar (B) 0.307...
