Question

The volume of a gas at 5.0 atm is 3.5 L. What is the volume of the gas at 7.0 atm at the same temperature?

025L
O5.0 L
O10. L
O 12L

Answer 1

0.25L

Step-by-step explanation:

Answer 2

10 L

Step-by-step explanation:

Boyle's Law

• states that the pressure exerted by a gas (of a given mass, kept at a constant temperature) is inversely proportional to the volume occupied by it
• P ∝
  `(1)/(V)`
• P₁V₁ = P₂V₂

Our values

• P₁ = 5 atm
• V₁ = 3.5 L
• P₂ = 7 atm

Using the equation

• 5 x 3.5 = 7 x V₂
• V₂ =
  `(35)/(3.5)`
• V₂ = 10 L
