1. The problem statement, all variables and given/known data I have a sealed container of volume v = x m^3, which holds a sample of y x 10^24 atoms of He gas in equilibrium. The distribution of speeds of the atoms is peaking at 110 m s^-1. How do I calculate the temperature and pressure of the He gas? Which equations would I use to calculate the average kinetic energy of the atoms? 2. Relevant equations I don't know where to start. 3. The attempt at a solution This is what I need help with.
