Me i will give brainliest and 20 !
1. which of the following statements is true?
the square root of the molecular weight of a gas is equal to its rate of diffusion.
the rate of diffusion of a gas in inversely proportional to the square root of its molecular weight.
the rate of diffusion of a gas is directly proportional to the square root of its molecular weight.
the square root of the molecular weight of a gas is not related to its rate of diffusion.
2. choose all that apply. solids, liquids, and gases can be distinguished by their:

molecular weight
shape
temperature
kinetic energy
mass
density
(you can select as many that are correct, if you have to, all of them)
3. list the 4 main components of air in their molecular form.

(just go under 3 put 1, then list it, 2 then list it and so on)
