Two seperate samples of argon gas are held seperate chambers connected with a valve in the middle. Chamber A has a bolume of 2.00 L, and contains 120 g of Ar at 650 K. Chamber B has a voulem of 5.00L and contains 60 g of Ar at 300K. ASSUMING IDEAL GASES, calculate 1. final temperature of these gases and 2. final pressure of the gas
