Answer:
B. 10 cubic inches
Explanation:
Boyle's Law: States that the volume of a given mass of gas is inversely proportional to its pressure provided that temperature is constant.
Mathematically, Boyle's law can be expressed as
P₁V₁ =P₂V₂......................... Equation 1
making V₂ the subject of formula in the equation above,
V₂ = P₁V₁/P₂ ..................... Equation 2
P₁ =initial pressure, V₁ = initial volume, P₂ = final pressure, V₂ = final Volume.
Given: P₁ = 5 psi, V₁ = 20 cubic inches, P₂ = 10 psi.
Substituting these values into equation 2
V₂ = (5 × 20)/10
V₂ = 10 cubic inches.
Therefore the new volume = 10 cubic inches
The right option is B. 10 cubic inches.
