Question

The freezing of water at 0C can be represented as follows: 
   H2O(l) <----> H2O(s) 
The density of liquid water is 1.00 g/cm3. The density of ice is 0.92 g/cm3. In 3-4 sentences explain why applying pressure causes ice to melt.

When applying pressure, would that increase or decrease the volume?

emmaleelooney · Answer

Increase?

joannablackwelder · Answer

Hm, no, when you squeeze something, it gets smaller (volume goes down)

emmaleelooney · Answer

I have trouble putting everything together in chemistry sorry.. But I'm trying.

joannablackwelder · Answer

It's cool :-) But does that make sense?

emmaleelooney · Answer

Yes, that does

joannablackwelder · Answer

Cool, and do you think squeezing it would change the mass?

emmaleelooney · Answer

... Yeah. I don't know if that's wrong but..

joannablackwelder · Answer

Ok, that's fair. The only way it could change the mass would be if some dropped (or dripped) out. Mass doesn't change when pressure is applied.

joannablackwelder · Answer

So, mass stays the same, but volume goes down. What would that do to the density?

emmaleelooney · Answer

Oh okay... Got that. Soooo the density would increase?

joannablackwelder · Answer

Yep :-)

joannablackwelder · Answer

And liquid water's density is larger than ice's.
