The concentration of particles (assume neutral hydrogen atoms) in interstellar gas is 1.0 particle/cm3, and the average temperature is about 15K . What is the pressure of the interstellar gas? How does it compare to the best vacuum that can be achieved on Earth (10?15atm)? This is much smaller than the minimum value for the best vacuum. This is much greater than the minimum value for the best vacuum. This is equal to the minimum value for the best vacuum.
