Two containers, x and y, both contain nitrogen gas at a temperature of 30° c and a pressure of 1 atm. the initial volume of each of the containers is v30 = 0.5 liters. the only difference between the two containers is that while container x has a piston that is sealed and cannot move, the gas in container y is allowed to expand against the surrounding atmosphere. qx is the amount of heat required to raise the temperature of the gas in container x by 10° c, and qy is the amount of heat required to raise the temperature of the gas in container y by 10° c. what is the difference between qx and qy? use 0°c = 273.15 k qx - qy =

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
