When a sample of a gas at a pressure of 200 kPa and constant volume is heated from 30°C to 80°C the pressure must be multiplied by

Question

a) 30/80

 

b) 80/30

 

c) 200/80

 

d) 303/353

 

e) 353/303

Answer 1

P1/T1  = P2/T2

200/303 = P2/353

P2 = (200)(353)/303

So the pressure is multiplied by the factor 353/303

Answer = e
