Two vessels connected by a valve of negligible volume. One container (I) has 2.8g of N2 at temperature T1(K). The other container (II) is completely evacuated. The container (I) is heated to T2(K) while container (II) is maintained at T2/3(K). volume of vessel (I) is half that of vessel (II). If the valve is opened then what is the weight ratio of N2 in both vessel (WI/WII)?
