Two different gases occupy the two bulbs shown here. Consider the process that occurs when the stopcock is opened, assuming the gases behave ideally.
(a) Draw the final (equilibrium) state.
(b) Predict the signs of ?H and ?S for the process.
(c) Is the process that occurs when the stopcock is opened a reversible one?
(d) How does the process affect the entropy of the surroundings?
