Would water molecules in Venus's atmosphere, whose temperature is 740 K, eventually es-cape into outer space? Note that a water molecule has a mass that is 18 times that of a hy-drogen atom. 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.
