Explanation:
1) Data:
a) V₁ = 38.2 liter
b) P₁ = 91 psi
c) V₂ = 77.4 liter
d) P₂ = ?
2) Formula:
According to Boyle's law, at constant temperature, the pressure and volume of a fixed amount of gas are inversely related:
PV = constant ⇒P₁V₁ = P₂V₂3) Solution:
Solve for the unknown: P₂ = P₁V₁ /v₂Substitute the values: V₂ = 91 psi × 38.2 liter / 77.4 liter = 44.9 9si ≈ 45 psi.Ответ:
