20) V₁ = 1248 ft³               T = 28.0°C

       P₁ = 0.988 atm       

      (a) V₂ = 978 ft³

            P₁V₁ = P₂V₂

            P₂ = P₁V₁ /V₂

            P₂ = 0.988 atm * 1248 ft³/978 ft³ = 1.26 atm

      (b) V₂ = 1435 ft³

            V₁/T₁ = V₂/T₂

            T₂ = V₂ * T₁/V₁ = 1435 ft³ * 301 K/1248 ft³ = 346 K = 73°C
