A)
Ti = 25 oC= (25+273) K = 298 K
Tf = 50 oC= (50+273) = 323 K
use:
Vf/Vi = Tf/Ti
Vf/Vi = 323/298
(Vf-Vi)/Vi = (323-298)/298
=0.084
volume has increased by 8.4 %
Answer: The volume should increase by about 10%.
B)
Ti = 25 oC = 298 K
Tf = 448 K
Pi = 0.92 atm
Pf = 2.7 atm
use:
Pi*Vi/Ti = Pf*Vf/Tf
Vf/Vi = Pi*Tf/(Pf*Ti)
Vf/Vi = 0.92*448 / (2.7*298)
Vf/Vi = 0.512
(Vf-Vi)/Vi = (0.512-1)/0.512
= -0.488
volume has decreased by 48.8 %
Answer: The volume should decrease by about 50%.
C)
Vf/Vi = Pi/Pf
Vf/Vi = 0.92/2.7
Vf/Vi = 0.341
(Vf-Vi)/Vi = (0.341-1)/1
(Vf-Vi)/Vi = -0.659
volume has decreased by 65.9 %
Answer:
The volume should decrease by about 40%
