Question

As a substance changes phase from gas to liquid to solid:

the spacing between molecules increases
its density generally increases
the spacing between molecules is not affected
it undergoes chemical change

Answer 1

I would say that its density generally increases

Answer 2

I know that D is wrong so we can cancel that one out

Answer 3

Ok i will give it a shot and see of it works :) thanks

Answer 4

You were right!

Answer 5

Yay me! Do you see why it is the right answer?

Answer 6

Because a solid generally has a higher density than a gas or a liquid?

Answer 7

Can you think of a substance that this trend doesn't hold true for?

Answer 8

Nothing comes to mind...

Answer 9

think about water and how ice cubes float in a glass of it. the reason the ice is floating is because it has a lower density than that of it water in liquid form.

Answer 10

Thanks for the medal buddy keep plugging away at the chemistry stuff

Answer 11

oh and ice is a solid

Answer 12

Thanks for the help! I understand how density works a lot better now :)

Answer 13

density is \(\sf \color{}{\frac{mass}{volume}}\) just think about that.
