Sample Questions and Solutions from PHet Gas Law Simulations Answer Key

Boyle’s Law Example

Question:

If a gas at 1 atm pressure occupies a volume of 10 liters, what will be its volume when the pressure is increased to 2 atm, assuming temperature remains constant?

Solution:

Using Boyle’s Law: P₁V₁ = P₂V₂

• P₁ = 1 atm
• V₁ = 10 L
• P₂ = 2 atm
• V₂ = ?

V₂ = (P₁V₁) / P₂ = (1 atm 10 L) / 2 atm = 5 L

Answer:

The new volume is 5 liters.

Charles’s Law Example

Question:

A gas at 300 K occupies 8 liters. What volume will it occupy at 600 K, assuming pressure remains constant?

Solution:

Using Charles’s Law: V₁/T₁ = V₂/T₂

• V₁ = 8 L
• T₁ = 300 K
• T₂ = 600 K
• V₂ = ?

V₂ = V₁ (T₂ / T₁) = 8 L (600 K / 300 K) = 16 L

Answer:

The volume will be 16 liters.
