Can't Judge a Powder B

I'd probably be on varsity if I didn't vomit during the tryouts one day

What does hygroscopic mean?

What does hygroscopic mean?

Hygroscopy is the ability of a substance to attract and hold water molecules from the surrounding environment through either absorption or adsorption with the adsorbing or absorbing material becoming physically 'changed,' somewhat: by an increase in volume, stickiness, or other physical characteristic of the material as water molecules become 'suspended' between the material's molecules in the process. While some similar forces are at work here, it is different from capillary attraction, a process where glass or other 'solid' substances attract water, but are not changed in the process, e.g. water molecules becoming suspended between the glass molecules.

How would you tell if a powder is hygroscopic?

[robotman]

whether or not it clumps.
If it is clumped in the container they give you of it it would obsorbe ambient H2O

[geekychic13]

what do you mean when you say it will absorb ambient water?

whether or not it clumps.
If it is clumped in the container they give you of it it would obsorbe ambient H2O

It was a reference to the definition of Hygroscopy

how do you place in this event?!! i've been doing this for around two years and i just dont seem to be able to place
even when i thought i got 113/120, i still got fifth place! this event is so easy that its hard to beat others out for a medal

make sure all of your observations are in fact OBSERVATIONS and not inferences.

Also look for superficial things like the bag number. We seriously got that question.
