What do we need to know to answer this fine question?
- 00:36
Hmm...well, it looks like a 'read the passage to find the answer' type question.
- 00:41
So... where does it say anything about salt being left behind in the distillation chamber?
- 00:46
Well... it says that "The reason that the solute is left in the distillation chamber
- 00:51
after the water is boiled away is that the solute and the water
- 00:56
possess different boiling points."
- 00:58
That... pretty much answers our question.
- 00:59
So, apparently, the solute is left in the chamber because the
- 01:02
solute and water possess different boiling points.
- 01:06
Wait...what's a solute again?
- 01:08
Yeah, no...it's not that gesture of respect. No.
- 01:11
A solute is the smaller component of a solution... the part that's dissolved into the solvent.
- 01:17
So in this case, the solute is the salt.
- 01:20
Looks like B is our answer -- the solute, or salt,
- 01:23
and the water have different boiling points.
- 01:25
As do the test administrators if they catch you
