A sealed tube which can withstand a pressure of 3 atmosphere is filled with air at `27^(@)C` and 760 mm pressure. Find the temperature above which it will burst.

Options

A. `81^(@)`C
B. `627^(@)`C
C. `900^(@)C`
D. `1173^(@)` C

Answer

B

Explanation

Sealed tube-constant Volume
`:. P_(1)/(P_(2))=T_(1)/T_(2) :.(760)/(3xx60)=(300)/(T_(2))`
`:. T_(2)=900 K=627^(@)C`
