Answer» <P>`6 V` `3 V` `1.5 V` `1 V` Solution :Given: Initial VOLUME `V_(1) = 3V` Initial pressure `P_(1) = 2` atmosphere Final pressure `P_(2) = 2P_(1) = 2 xx 2 = 4` atmosphere According to the Boyle's law we have `P_(1)V_(1) = P_(2)V_(2)` (where `V_(2)` is the final volume of gas) `or 2 xx 3V = 4xxV_(2)` or `V_(2) = 1.5V`.
