The pressure exerted by a gas in sealed container is 100kPa at 17oC. It was found that the container might leak if the internal pressure exceeds 120kPa. Assuming constant volume, at what temperature in oC will the container start to leak?



P2=120 kPa

T=17oC  = 290K


we know that at constant volume..

p1/T1 =  p2/T2


T2 = T1 x p2/p1

T2 = 290 x 120/100 = 348 K = 75oC
