  • Pressure
  • Boyle's Law: P₁V₁ = P₂V₂

Step-by-step explanation:

Step 1: Define

[Given] P₁ = 97.0 kPa

[Given] V₁ = 0.4 L

[Given] P₂ = 178 kPa

[Solve] V₂

Step 2: Solve for V₂

  1. Substitute in variables [Boyle's Law]: (97.0 kPa)(0.4 L) = (178 kPa)V₂
  2. [Boyle's Law] Multiply: 38.8 kPa · L = (178 kPa)V₂
  3. [Boyle's Law] [Division Property of Equality] Isolate V₂ [Cancel units]: 0.217978 L = V₂
  4. [Boyle's Law] [Volume] Rewrite: V₂ = 0.217978 L
  5. [Boyle's Law] [Volume] Round: V₂ ≈ 0.22 L
