1.	Two chambers, one containing m_1g of a gas at P_1 pressure and other containing m_(2)g of a gas at P_2 pressure are put in communication with each other. If temperature remains constant, the common pressure reached will be
Answer» `(P_1 P_2 (m_1 + m_2) )/( P_1 m_2 + P_2 m_1)` `(P_1 P_2 (m_1 - m_2) )/( P_1 m_2+P_2 m_1)` `(P_1 P_2 (m_1 + m_2) )/( P_1 m_1 + P_2 m_2) ` `(P_1P_2 (m_2 - m_1) )/( P_1 m_1 + P_2 m_2)` ANSWER :A
