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.

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:

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
