Question

The density of ocean water increases as:


pressure decreases.


temperature increases.


all of the above


salinity increases.

Answer 1

So what would happen if you increase the temperature of water?

Answer 2

So does the pressure?

Answer 3

well, think about boiling water... what is happing to water when you boil it?

Answer 4

Temperature increases. XD

Answer 5

Well, you would be able to observe steam coming out of the pot, right?

Answer 6

yep

Answer 7

So would we say that density is increasing?

Answer 8

Yeah

Answer 9

not necessarily. water will keep its density even when boiled. So you can eliminate the temperature answer

Answer 10

Oh ok :)

Answer 11

do you think that pressure plays a role in the density of water?

Answer 12

Im thinking no.

Answer 13

You are right.

Answer 14

So, if that is the case then we can say that salinity increases the density of water because the salt crystals bind to water molecules which makes the density of water increase because it has more mass than it did with H2O molecules. Now you have H2O+ NaCl

Answer 15

Awesme :)
