Multiple Choice
Would a nitrogen atom in Venus's atmosphere, whose temperature is 740 K, eventually escape into outer space? Note that a nitrogen atom has a mass that is 14 times that of a hydrogen atom.Recall that atoms eventually will escape if their average velocity is greater than 1/6 times the escape velocity of the planet.The escape velocity of Venus is 10 km/s.For comparison, a hydrogen atom has an average velocity of 2.5 km/s at a temperature of 300 K.
A) The average velocity of nitrogen atoms is 0.4 km/s, and nitrogen does not escape.
B) The average velocity of nitrogen atoms is 1.0 km/s, and nitrogen does not escape.
C) The average velocity of nitrogen atoms is 1.0 km/s, and nitrogen escapes.
D) The average velocity of nitrogen atoms is 4.5 km/s, and nitrogen does not escape.
E) The average velocity of nitrogen atoms is 4.5 km/s, and nitrogen escapes.
