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

Sagot :

Answer:

10 L

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 ∝ [tex]\frac{1}{V}[/tex]
  • 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 = [tex]\frac{35}{3.5}[/tex]
  • V₂ = 10 L
