If a cylinder containing a gas at high pressure explodes, the gas undergoes

A gas cylinder containing cooking gas can withsand a pressure of 14.9 atmosphere. The pressure gauge of the cylinder indicates 12 atmosphere at 27^(@)C . Due to a sudden fire in the building the temperature starts rising. At what temperature will the cylinder explode ?

(A) A closed cylinder containing high pressure gas tends to rise against gravity when the gas is allowed to escape through an orifice at the bottom (R) The velocity of escaping gas develops an upward thrust proportional to the area of cross-section of the orifice
