[Question] disc weights

[Nasty Nate]

Every Innova disc I have weighs 2 grams more than the listed weight. Most of my other discs are around 1-2 grams heavier than advertised.

Do you live on earth?!

Most of the time.

I stand corrected, I never thought of water vapor as gas, but always as a suspended solid. I'm always eager to learn from anyone who knows more than I do, thanks professor.

It doesn't matter unless a jack hole wants your discs weighted during a tournament.

I've weighed a bunch of my discs before and while some were off most are spot on to what's listed. The ones that are off have been both heavier and lighter than the claimed weights. I think your scale is off, especially considering that from what you've said the deviation is pretty consistent.

Ted did no such thing,he threw out the term adsorb. My understanding of that term is that it occurs only on the surface of the material acting as the adsorbant. Seems as though that would hardly be enough water molecules to change the weight of a disc by even a fraction of a gram. What's your understanding of the term "adsorbtion"? I'm always eager to learn from anyone who knows more than I do. At what point after the molding process do discs absorb weight? How do they do that? Ted says adsorb, you say absorb. Are you both correct?

ab·sorb
transitive verb \əb-ˈsȯrb, -ˈzȯrb\

: to take in (something, such as a liquid) in a natural or gradual way

: to draw in (heat, light, energy, etc.)

: to learn (something)

Adsorption is different than absorption. Although Ted's post does say aBsorb.

Unrelated; here is chart for Nylon (polyamide) that has moisture content by weight as the independent variable. Some plastics won't be affected nearly as much (POM for instance). I don't know what discs are made out of.

FYI, if you are soaking a disc for only one day to test this, it better be HOT.

Very nice. Doesn't answer my question though. What's your understanding of the term "adsorbtion"? I'm always eager to learn from anyone who knows more than I do.

The post I saw by Ted used both words. How many days should The Hammer soak his discs if temperatures are not overly hot?

 

[notapro]

With room temperature water, 100 hours/four days.

You know you can use Google, too.

ad·sorp·tion
noun \ad-ˈsȯrp-shən, -ˈzȯrp-\
Definition of ADSORPTION
: the adhesion in an extremely thin layer of molecules (as of gases, solutes, or liquids) to the surfaces of solid bodies or liquids with which they are in contact

FYI....I'm not the one who doubts this, so I don't really care to spend any of my time doing experiments. Thanks for volunteering me though.
