7.00 kg of carbon monoxide undergoes a constant volume process from 100 kpa and 7°c until the pressure is 400 kpa. a) find the temperature of the gas at the final state in °c b) find the change in internal energy, per unit mass. c) find the heat transfer for this process, per unit mass d) if the surroundings are at 700°c, is this process reversible, irreversible, or impossible? the universal gas constant is 8.314 kj/kmol-k for carbon monoxide the molecular weight is 28. find other properties in table a-20.

While strolling downtown on a saturday afternoon, you stumble across an old car show. as you are walking along an alley toward a main street, you glimpse a particularly stylish alpha romeo pass by. tall buildings on either side of the alley obscure your view, so you see the car only as it passes between the buildings. thinking back to your physics class, you realize that you can calculate the car's acceleration. you estimate the width of the alleyway between the two buildings to be 6 m. the car was in view for 0.6 s. you also heard the engine rev when the car started from a red light, so you know the alpha romeo started from rest 4 s before you first saw it. find the magnitude of its acceleration.
