[Lex Computer & Tech Group/LCTG] Mystery I'm trying to figure out

[arnold peterson]

I wonder if heat is produced by this reaction, then I could understand a
weight loss.

There is another possibility. I have a food scale that I weigh my ground
coffee. Sometimes it seems like the scale takes time for the reading to
settle down.

I find that when I use a larger amount of coffee this is less of a
problem.  le: If using 20-25 g this is less likely to happen than when I
use 10g, which happens almost all the time.

The scale I use is a weight watchers scale.

I think a balance scale might be a way for another more reliable method.

I think this is a physics problem, of the scale. My scale likes to move in
2 g increments.  -arnie
