P. 4470. The containers of A and B are connected by a short and thin tube. The volume of container A is three times as much as that of container B. Initially in both containers there is air at a temperature of 20 oC and at a pressure of 105 Pa. Then container A is heated to a temperature of 100 oC, and is kept at this temperature while the temperature of B is still 20 oC. By what percent does the mass of the gas in each container change, and what will the pressure be in them?
