The volume of a gas at 30^ C temperature and 760 ~mm of Hg pressure is 100 cc . Then its volume at the same temperature and 400 ~mm of Hg is

Step-by-step solution

Given, initial volume =100 ~cm ^3 Initial pressure =760 ~mm of Hg Initial temperature =30^ C And, final temperature = Initial temperature So, change is isothermal. Also final pressure =400 ~mm of Hg Now, for an isothermal change p_i V_i=p_f V_f array ll 760 100=400 V_f & V_f= 760 100 400 array =190 ~cm ^3=190 cc [ lcm ^3=1 cc ]
