1.	An open steel vessel has an ideal gas at 27^@C. What fraction of the gas is escaped if the vessel and its contents are heated to 127^@C? (neglect the expansion of steel)
Answer» Solution :LET one mole of the gas is taken in the vessel of constant volume (V). From the ideal gas equation, at two conditions of temperature, `n_(1)T_(1) = n_(2)T_(2)` `1 xx 300 = n_(2) xx 400` Number of moles finally LEFT in the vessel `(n_(2))` `n_(2) = (300)/(400) =(3)/(4)` THe fraction of gas escaped from the vessel UPON HEATING ` = 1-3//4 = 1//4`
