A gas tanker carries helium gas at a pressure of 2.5 atmospheres at 25oC. The tanker can withstand a maximum pressure of 10 atmospheres. It collides with a truck and catches fire. According to the above information the tanker will blow up after the collision or it will catch fire. Explain. (Melting point of iron - 1535oC)

Given:

A gas tanker carries helium gas at a pressure of 2.5 atmospheres at 25oC.

The tanker can withstand a maximum pressure of 10 atmospheres.

The pressure built up in the tanker at melting point of iron is:
P1 = 2.5 atm, P2 = ? , T1 = 25oC, T2 = 1535oC = 1808 K

Since, the pressure of the gas in the tank is much more than 10 atm at the melting point, the tank will blow up before reaching the melting point.
