1.	The pressure exerted by 12 g of an ideal gas at temperature t^(@)C in a vessel of volume V litre is one atm. When the temperature is increased by 10 degree at the same voume, the pressure increases by 10%. Calculate the temperature t and volume V (Molecular weight of the gas=-120).
Answer» Solution :Applying PV=nRT In the 1 st CASE,`1xxV=(12)/(120)xxRxx(273+t)""`……….(i) In the 2nd case,`1.1xxV=(12)/(120)xxRxx(283+t)""`………..(ii) DIVIDING (i) by (ii), `(1)/(1.1)=(273+t)/(283+t)` On SOLVING it gives `t=-173^(@)C`. Putting in (i), `"" V=0.1xx0.082xx100=0.82" litre"`
