Physical Science Gas laws

Question

500 ml of argon is held in a container under 20 atm of pressure. What will the volume of the gas be if the pressure is decreased to 14 atm

Answer 1

Assuming the temperature remains constant, you can use Boyle's Law:

 

P₁V₁ = P₂V₂

• P₁ = starting pressure = 20 atm
• V₁ = starting volume = 500 ml
• P₂ = final pressure = 14 atm
• V₂ = final volume = ? ml

 

Plug in the numbers and solve for V₂.
