CBSE Class 11-science Answered
A steel cylinder contains a gas at 250kpa and at 27°c. The cylinder can withstand a pressure of (10)*6 Pa. Due to fire, the temperature of the room rises. If melting point of the cylinder is 1527°c, predict whether the cylinder will blow up before it melts or not ?

Expert Answer
Given:
P1 = 250 kPa
= 250 × 103 Pa
T1 = 27 °C
=27+273
= 300K
P2 = 106 Pa
T1 =?
The melting point of the cylinder is 1527 K and when pressure is of 106 Pa the temperature is 1200 K.
Therefore the cylinder will blow up before it melts.
