"Men occasionally stumble over truth, but most of them pick themselves up and hurry off as if nothing had happened." -- Winston Churchill
Special Significant Figure Note: Textbook authors and teachers sometimes don't pay slavish attention to significant figure rules in the gas laws unit. However, the key is to be reasonable. For example, suppose 100 K is used in a multiplication, so you think the answer should have only one significant figure. Wrong! 100 K is a value easily measured in the lab (well, not a high school lab) to three or four significant figures. ChemTeam students in the classroom are advised to think of this value as having three significant figures. Check with your classroom teacher on this point and follow what you are told.
