What is the formula for Boyle's Law?

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

What type of relationship to pressure and volume have?

• direct

• no relationship

• inverse

• I don't know

When Pressure increases then the Volume must...

• Increase
• decrease

Which container will have a lower pressure?

• left
• right
• they both have the same pressure
• I don't know

IF we are using Boyles' law and our Pressure goes UP, what must our volume do?

• Go UP

• Go DOWN

• Stay the same

• Wrong law.

When Pressure increases then the Volume must...

• Increase

• decrease

According to Charles Law, if Temperature of a gas increases Volume will also....

• Increases

• Decreases

• Stays the same
