A steel tank containing air at 15 pressure at `15^(@)C` is provided with a safety valve that will yield at a pressure of 30 atm. To what minimum temperature must the air be heated to blow the safety valve ?

Text Solution

Verified by Experts

The correct Answer is:
C
`(P_(1))/(T_(1))=(P_(2))/(T_(2)), i.e.,(15" atm")/(288 K)=(30" atm")/(V_(2))" or "T_(2)=576 K=(576-273)^(@)C=303^(@)C`
