If it has enough kinetic energy, a molecule at the surface of the Earth can escape the Earth’s gravitation.
The acceleration of gravity is 9.8 m/s2, and the Boltzmanns’ constant is 1.38066 × 10−23 J/K.
minimum kinetic energy needed to escape in terms of the mass of the molecule m, the free-fall acceleration at the surface g, and the radius of the Earth R.
1. Kmin = 1 m g R 3
2. Kmin = 1mgR 2
3. Kmin = 2 m g R 1
4. Kmin = √2 m g R 5. Kmin = m g R
