Would water molecules in venus’ atmosphere, whose temperature is 740 k, escape into outer space? a water molecule has a mass that is 18 times that of a hydrogen atom. recall that gas eventually will escape if the average velocity of its atoms is greater than 1/6 times the escape velocity of the planet. the escape velocity of venus is 10 km/s.

Ответ:
The water molecule cannot escape, since the average velocity of the water molecules is less than one sixth of the escape velocity of venus.
Explanation:
The average speed of gas molecules is given by:
R is the gas constant, T is the temperature and M the molar mass of the gas.
We know that a water molecule has a mass that is 18 times that of a hydrogen atom:
So, we have:
The water molecule cannot escape, since the average velocity of the water molecules is less than one sixth of the escape velocity of venus:
