At STP: P₁ = 760 mmHg, T₁ = 273 K, V₁ = 720 cm³
Final: P₂ = 698 mmHg, T₂ = ? K, V₂ = 1000 cm³
For a fixed amount of gas: P₁V₁/T₁ = P₂V₂/T₂
Final temperature, T₂ = T₁ × (P₂/P₁) × (V₂/V₂) = (273 K) × (1000/720) × (698/760) = 348 K = 75°C
Final: P₂ = 698 mmHg, T₂ = ? K, V₂ = 1000 cm³
For a fixed amount of gas: P₁V₁/T₁ = P₂V₂/T₂
Final temperature, T₂ = T₁ × (P₂/P₁) × (V₂/V₂) = (273 K) × (1000/720) × (698/760) = 348 K = 75°C
