Subject: Basic Chemistry
You have two balloons of the same temperature: one balloon is full of Helium and the other is full of Argon. What is one similarity and one difference between the condition of the atoms in these balloons?
Both balloons have the same average kinetic energy per atom (as represented by the uniform temperatures). However, as Argon is a heaver atom than Helium, the Helium atoms must have a higher average velocity. (KE=1/2 mv^2)
