Prove me wrong: So you know how you can't really breathe in smoke or it'll make u sick right? and let's use wood for example, when you burn wood, it kinda shrinks, right? so when it burns, it's kinda like it's evaporating, and when something evaporates, it has to go somewhere, right? so, in conclusion, the reason you cant breathe in the smoke from wood is that if you do, a piece of wood will form in your lungs and kill you.

Oxygen gas enters well-insulated diffuser at 25 lbf/in.2, 420r, with a velocity of 860 ft/s through a flow area of 1.6 in.^2. at the exit, the flow area is 12 times the inlet area, and the velocity is 19 ft/s. the potential energy change from inlet to exit is negligible. assuming ideal gas behavior for the oxygen and steady-state operation of the diffuser, determine the following: (a) the exit temperature, in r(b) the exit pressure, in lbf/in.^2 (c) the mass flow rate, in lb/s
