One liter of argon gas at 300 k is expanded against constant external pressure from 10 to 100, at which point mechanical equilibrium is achieved. after the expansion, the temperature of the gas has fallen to 270 k. detemine q, w, ae and ah for this process. then do the same calculation, assuming molecular hydrogen vapor. treat both ar and h2 as ideal gases.

Plz mark brainliest 30 points1) find the momentum of a 12 kg snowball that is rolling with a velocity of 9 m/s.2) an 8 ball with a mass of .5 kg is sitting at rest. it is hit by the cue ball (1 kg) traveling at 2.5 m/s. if the cue ball is at rest after the collision, how fast is the 8 ball traveling after the collision? 3) two football players are running toward each other. if the offensive player is 75 kg and is running 8 m/s, how fast must the 60 kg defensive player run in order for the two players to hit and stop?
