Boyles and Charles Laws

What is the formula for Boyle's Law?

• P₁V₁=P₂V₂
• P₁V₁/P₂V₂
• P₁V₂=P₂V₁
• P₁/V₁=P₂/V₂

When Pressure increases then the Volume must...

• Increase
• decrease

What is the new volume of the gas if the pressure on 350 L of oxygen at 720 mm Hg is decreased to 600 mm Hg?

• 420 L
• 29.16 L
• 4200.0 L
• 291.6 L

A gas at a volume of 4 liters is at a pressure of 2 atm. The volume is changed to 16 Liters, what must the new pressure be?

• 2 atm
• 12 atm
• 10 atm

LeGarrette Blount decides to go scuba diving while on vacation in Mexico. As he swims deeper into the ocean, the pressure pushing on him increases. Based on the relationship in Boyle’s law, what would happen to the volume of a LeGarrette’s lungs with this increase in pressure?

• volume of the lungs would increase
• volume of the lungs would have no change
• volume of the lungs would double
• volume of the lungs would decrease

What is the formula Charles' Law?

• V = T
• VT = VT
• T₁ / V_{1 =} T₂ / V₂
• V₁ / T₁ = V₂ / T₂
