Question

Diffusion occurs faster in gases than in liquids because _____.

the particles are moving faster
the particles are further apart
the particles are moving slower
there are more inter-molecular attractions between particles

Answer 1

The correct answer to go in the blank would be A) The particles are moving faster.

Answer 2

the particles are moving faster

Step-by-step explanation:

As we know that diffusion means the rate of escape of gas from small opening.

So here the diffusion rate is basically related to the speed of gas molecules to escape out of the closed container.

So here rate of diffusion is given as

`Rate = \sqrt{(P)/(\rho)}`

so it depends on pressure of gas and density of gas.

Also we know that gas molecules are loosely bounded to each other as we compare the bonding between molecules of liquid.

So here we will say that correct answer is

the particles are moving faster
