How do you tell if a powder is hygroscopic? (procedures)
How do you test conductivity if you aren't allowed to bring a multimeter? (tester used)
A) Look in the 2007 test packet (2006 tests). There is an excellent description of the experiment that they were looking for testing for hygroscopic-ness on the CJAP test answer key.
B) Why wouldn't you be allowed to bring a multimeter? It says in the rules that a conductivity tester is allowed?
I asked the FAQ on national science olympiad page and they said you can't bring a multimeter. See here: http://soinc.org/node/477
Also what is the link to the "2007 test packet (2006 tests)".
