Two flask of equal volume are connected by a narrow tube (of negligible volume) are at `27^(@)C` and contain 0.7 moles of `H_(2)` each at `0.5` atm. One of the flask is then immersed into a bath kept at `127^(@)C`, while other remains at `27^(@)C`. If number of moles of `H_(2)` in flask 1 and flask 2 finally, are a and b respectively, then calculate value of `10 xx |a-b|`.
