Attendance 03/26: Boyle's & Charles's Law

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

(Boyle's Law) 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

What is the formula Charles' Law?

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

(Charles Law) There are 65 liters of helium in a balloon at 35 K. If the temperature of the balloon is increased to 40 K, what will the new volume of the balloon be?

• 40 L

• 70 L

• 74.3 L

• 75.9 L
