A rigid and insulated tank of 3m^(3) volume is divided into two compartments. One compartment of volume of 2m^(3) contains an ideal gas at 0.8314 Mpa and 400 K while the second compartment of volume of 1m^(3) contains the same gas at 8.314 Mpa and 500 K. If the partition between the two compartments is rptured, the final temperature of the gas is :

A container of volume 2L is seperated into equal compartments. In one compartment, one mole of an ideal monoatomic gas is filled at 1 bar pressure and the other compartment is completely evacuted. A pihole is made in the seperator so gas expands to occupy full 2 L and heat is supplied to gas so that finally pressure of gas equals 1 bar. Then :

A container is divided into two compartments. One compartment contains 2 moles of N_(2) gas at 1 atm and 300 K and other compartment contains H_(2) gas at the same temperature and pressure. Volume of H_(2) compartment is four times the volume of N_(2) compartment [Assuming no reaction under these conditions] Calculate the final total pressure if partition between two compartments is removed.

A container is divided into two compartments. One compartment contains 2 moles of N_(2) gas at 1 atm and 300 K and other compartment contains H_(2) gas at the same temperature and pressure. Volume of H_(2) compartment is four times the volume of N_(2) compartment [Assuming no reaction under these conditions] If the container containing N_(2) and H_(2) are further heated to 1000 K, forming NH_(3) with 100% yeild calculate the final total pressure.
