Here's your shmoop du jour... with extra crackers...

00:07

Hit pause and take a gander at the following passage.

00:09

Don't forget to affix your goggles first.

00:12

You don't want to get any knowledge in your eyes.

00:24

Which of the following is most likely NOT a critical component of the distillation chamber?

00:29

And here are the potential answers...

00:35

This question is all about distillation chambers.

00:38

Woohoo! Fun times! Wait...what are distillation chambers again?

00:43

Scientists use distillation apparatuses to separate components.

00:50

In this case, the liquid is boiled, leaving any precipitate

00:54

that was once dissolved in the solution.

00:57

Liquid water turned into water vapor.

00:59

That must mean that the distillation chamber

01:01

has to have a hole for the water vapor to escape.

01:04

So we can get rid of answer A. And, if we think about how liquid is boiled,

01:08

we can get rid of C also.

01:10

The chamber has to have a source of heat for the water to boil, so heating IS a critical component.

01:15

Hmm, seems like an important part of the distillation

01:18

chamber is... the chamber itself. Otherwise, we wouldn't have a place to do our distilling.

01:24

So B is pretty important. It is in the name of the thing, after all.

01:28

So that leaves us with D, filter paper.

01:30

The chamber doesn't need filter paper to function...the salt would fall right through it anyway.
