A gas eventually will escape from a planet's atmosphere if the average velocity of the atoms exceeds 1/6 times the escape velocity of the planet.If the average velocity of water vapor in Venus' atmosphere is 0.9 km/s,would it eventually escape? Venus' mass is and its radius is 6,050 km.
A) Water vapor would escape because 1/6 times the escape velocity is 0.51 km/s.
B) Water vapor would not escape because 1/6 times the escape velocity is 1.7 km/s.
C) Water vapor would escape because 1/6 times the escape velocity is 0.42 km/s.
D) Water vapor would not escape because 1/6 times the escape velocity is 2.6 km/s.
