Consider a source that emits an alphabet with three symbols a, b, c having probability distributions as follows - p(a) = 0.625, p(b) = 0.125, p(c) = 0.25 construct a huffman code and calculate its average code length. (2 points) for this three-symbol vocabulary, how many huffman codes are possible. what are they? (2 points) is the code you have defined optimal - give reasons! if not, what can you do to improve upon this. show a solution by an example computing the avg. code length. (6 points)

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.
