Question

help to solve 7.9 problem plz....... (by Charles law)

Answer 1

Hey buddy!!!!

Here si your answer

=====================================

p1V1/T1 = p2V2/T2

here the volume is assumed to be constant because there is cylinder

so V1 = V2

Now,

p1 = 13.7 MPa; T1 = 23 + 273 = 296 K

p2 = ?

T2 = 450 +273

= 723 K

13.7 MPa/296 K = p2/723 K

p2 = 13.7 MPa(723 K)/296 K

= 33.5 MPa

1 atm = 101.325 kPa = 0.101325 MPa

33.5 MPa = 331 atm

=====================================

Hope this will help you
