EXAM 4 CHEMISTRY 113
EXAM 2024
100% CORRECT ANSWERS
, 1. Boyle's Law: what quantity relating pressure P and volume V is constant?
ANSWER: P X V
2. A 12-liter tank contains helium gas pressurized to 160
What size tank would be needed to contain this same amount of helium at
atmospheric pressure (1 atm)?
ANSWER: P1V1=P2V2
P1 = 160
V1= 12
P2= 1
V= ?
160(12)=(1)(?)
=1920
3. How many 3-liter balloons could the 12-L helium tank pressurized to 160
Atm fill?
Keep in mind that an "exhausted" helium tank is not empty. In other words,
once the gas inside the tank reaches atmospheric pressure, it will no longer be
able to fill balloons.
