With #3 is it meaning sublimation or solid?
#1 is C?
#2 is B?

Answer 1

Is that a phase diagram?

Answer 2

3i think is the triple point when all 3 phases (gas liquid, solid) can exist

Answer 3

It's a phase diagram

Answer 4

I'm not sure it's giving me that as an option. It's wanting me to match the numbers up with the pictures.

Answer 5

oh ill say 1 a, 2 d, 3 c

Answer 6

Mkay but what positions are these suppose to be exactly? It's getting me confused.

Answer 7

Cause I thought maybe 1 was a solid?

Answer 8

from my textbook it looks like 1 is where it would be solid or liquid, 2 is solid or vapor, and 3 is either the triple point or solid

Answer 9

the pictures are throwing me off...w and c look pretty clsoe

Answer 10

a and c I mean

Answer 11

Okay so is it asking for melting point, freezing, condensation, sublimation etc?

Answer 12

phase diagrams show where a substance can exist as a solid, liquid, or gas. form there you can derive the meltimg, booling, condenstation, eveaporation etc....don't know exactly what question you werwe givem?

Answer 13

Because the question is asking "Match each numbered point in the phase for compound Q with the correct molecular depiction below".

Answer 14

Sorry forgot to include the question

Answer 15

hmmm that's ok...trying to figure out the pictures exactly and all..i thihkn you have the right idea its just htat the diagram sucks

Answer 16

Yeah. The ones in the homework I'm given are moving so it's even worse.

Answer 17

oh jeez

Answer 18

To me A looks like it's trying to be a liquid and B is a gas....C is a solid and D is suppose to be sublimation or something of the sort.

Answer 19

yeah I would agree...so matching that to the phase diagram would be A matches to 1 C matches to 3, and B matces to 2?

Answer 20

So 1 is liquid and 2 is gas and 3 is a solid?

Answer 21

i think so

Answer 22

im studying he same stuff for a chem test right now,lol

Answer 23

Good luck on your test and thanks for helping out

Answer 24

thank you and youre welcome.. i hope it works out for you :-)

Answer 25

Thanks

Answer 28

@staldk3 this is the phase diagram for water right?

Answer 29

Right. I figured it out though. It was just tricky trying to see what they wanted.

Answer 30

well, number's 3,2,1 mean equilibrium between two phases

Answer 31

It's pretty straightforward. point three means, equilibrium between gas and solid. if we cross that line, we get sublimation, going form gas to liquid because we haven't gone through the liquid phase.

Answer 32

if we're in the solid phase, under a certain temperature and pressure we can go straight to the gas phase without going to liquid phase. see below:
