A.
In a common classroom demonstration, a balloon is filled with air and submerged into liquid nitrogen. The balloon contracts as the gases within the balloon cool. Suppose the balloon initially contains 3.15 L of air at a temperature of 30.0 ∘C and a pressure of 0.991 atm .
Calculate the expected volume of the balloon upon cooling to -196 ∘C (the boiling point of liquid nitrogen).
B.
When the demonstration is carried out, the actual volume of the balloon decreases to 0.64 L . How well does the observed volume of the balloon compare to your calculated value?
