Robert Boyle is known for Boyle's law, which states that the pressure of a fixed amount of gas at constant temperature is inversely proportional to its volume. The formula for Boyle's law describes the fundamental relationship between gas pressure and volume it occupies. Three sample problems are provided to demonstrate how to use Boyle's law to calculate gas pressure or volume given one variable.

9. SAMPLE PROBLEMS

10. SOLVE…
•Problem #1: A gas occupies 12.3 liters
at a pressure of 40.0 mmHg. What is
the volume when the pressure is
increased to 60.0 mmHg?

11. SOLVE…
•Problem #2: 4.35 L of a gas is at 1.16
atm. What pressure is obtained when the
volume is 9.3 L?

12. SOLVE….
•A balloon was inflated to a volume of 5.0
liters at a pressure of 0.90 atm. It rises to
an altitude where its volume becomes
25.0 liters. What is the new pressure?
