Problem: Suppose we have two monoatomic gasses, neon and argon. We cool the neon gas to 200 K in a 5 m 3 room, while the argon gas it put into a 0.25 m 3 balloon and left outside, where the temperature is 27 oC. Assuming the room is at atmospheric pressure, 1x10 5 Pa, if the balloon is brought into the room filled with argon and shrinks as it reaches equilibrium, (a) What is the initial, average energy per particle of each gas? (b) What is the final, average energy per particle of each gas? (c) What is the final temperature of the room?
