Dropping one at a time
A helium-4 atom falls from a height h into a tank of gaseous helium atoms at 300 K. What is h in meters if the temperature of the helium atoms remains at 300 K after the falling atom enters the tank?
Details and assumptions
- The acceleration of gravity is \(-9.8~m/s^2\).
- As the atom falls it is in vacuum.
- The atom starts from rest.
