Correct answer: (C) 310 cc. Given initial volume V_1=300 cc; initial temperature T_1=27℃=300 K, initial pressure p_1=620 mm, final temperature T_2=47℃=320 K and final pressure p_2=640 mm. We know from the general gas equation p_1V_1/T_1=p_2V_2/T_2 =(620×300)/300=(640×V_2)/320 =310 cc where, V_2 is the final volume of the gas
