A steel tank containing helium is cooled to 15◦C. If you could look into the tank and see the gas molecules, what would you observe? 1. The gas molecules would still be uni- formly distributed around the tank because gases expand to fill up the whole volume due to their constant molecular motion. 2. The gas molecules would become uni- formly distributed near the entire wall of the tank because the molecules would try to es- cape the container due to their kinetic energies. 3. The gas molecules would have higher ki- netic energies and lower velocities, thus creat- ing no net change. 4. The molecules would sink to the bottom of the tank because of the loss of pressure. 5. The molecules would move to the center of the tank because their velocities would be lower, thus giving them less pressure.
