Q-3: n vehicles occupy squares (1, 1) through (n, 1) (i. e., the bottom row) of an n x n grid. the vehicles must be moved to the top row but in reverse order; so the vehicle i that starts in (i, 1) must end up in (n β i + 1, n). on each time step, every one of the n vehicles can move one square up, down, left, or right, or stay put; but if a vehicle stays put. one other adjacent vehicle (but not more than one) can hop over it. two vehicles cannot occupy the same square. calculate the size of state space as function of n.

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg β’ k, determine for the air the amount of entropy produced, in kj/k
