A fire extinguisher has a pressure of 12 atm at 25∘C.What is the final pressure, in atmospheres, when the fire extinguisher is used at a temperature of 63 ∘C, if Vand n are constant?

P=

Expert Solution

Intial final

T1 = 25C⁰ = 25+273 = 298K T2 = 63C⁰ = 63+273 = 336K

P1 = 12atm P2 =

P1/T1 = P2/T2

P2 = P1T2/T1

= 12*336/298 = 13.53atm>>> asnwer
