An iron cylider contains helium at a pressure of `250 kPa` at `300 K` The cylinder can withstand a pressure of `1 xx 10^(6)` Pa The room in which cylinder is placed catches fire Predict whether the cylinder will blow up before it melts or not melting point of cylinder `=1800 K` .

Text Solution

Verified by Experts

`P_(1) = 250 k Pa, T_(1) = 300 k , P_(2) = ? T_(2) = 1800K`
Applying pressure - temperature law, `(P_(1))/(T_(1)) = (P_(2))/(T_(2)) , (250)/(300) = (P_(2))/(1800)` or As the cylinder can withstand a pressure of `10^(6) Pa = 10^(3) kPa = 1000` blow up.
