2 For A gas P, look PA vi : 2L For B gas 2 L Vi Pi 200 K PA is constat since the temperatur PV, 2 Pava for gas A va altal = 4L. . Pa PIVI va look Pa x 2. 4. sokPa. for B. gas Va 2 4 L Pa = 200 kPa x2. 4 100 kPa. formed by opening the Total pressure of gas c. Value P.(A) & Palo) 50kPa & cookPa 1150 kPa
