Teacher’s Notes—Ideal Gas Law

Constant Temperature, Sample Data and Analysis

V

0

= 3.6 cc

Among different lab groups or over several trials you may find that calculated values of V

0

vary

by 1 cc or more. This may look like a very large uncertainty, but, since it is added to the total
volume of gas (40 to 60 cc) the absolute uncertainty, rather than the relative uncertainty, should be
considered.
