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's atmosphere is 0.9 km/s, would it eventually escape into outer space? Note that Venus's mass is 5 × 1024 kg, 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. e. Water vapor would escape because 1/6 times the escape velocity is 1.3 km/s.
