Volume of the gas = 2.5 L = constant
For a fixed amount of gas with constant volume: P₁/T₁ = P₂/T₂
Final pressure, P₂ = P₁ × (T₂/T₁ ) = (7.50 kPa) × (210/420) = 3.75 kPa
For a fixed amount of gas with constant volume: P₁/T₁ = P₂/T₂
Final pressure, P₂ = P₁ × (T₂/T₁ ) = (7.50 kPa) × (210/420) = 3.75 kPa
