1.	An iron tank contains helium at a pressure of 2.5 atmoshpere at 25^(@)C. The tank can withstand a maximum pressure of 10 atmosphere. The building in which tan has been places cathes. Fire- predict whether, the tank blow up first or melt. (MP o iron= 1535^(@)C).
Answer» Solution :Thus `P_(1)=25 ATM"" P_(2) ? T_(1)=25^(@)C=298K` `T_(2)=1535^(@)C =1808K` `(P_(1))/(T_(1))` thus, `P_(2)(P_(1)T_(1))/(T_(1))=(25xx1808)/(298)=15*16 "atm"` Since, pressure of the gas in the tank is MUCH more than 10 atm at the melting POINT. Thus, the tan will blow up befor reaching the melting point.
