1. From problem statement, we want to find bP / T g v
.
Using the product-rule,
FG PIJ FG vIJ FG PIJ
H T K H T K H v K
v
P T

By definition,
F I

P G J
v H T K P

and
F vI

T G
v H P K
J T

Then,
F P I P 1.8  10 5
GH T KJ T 5.32  10 6
33.8 bar DC-1
v

Integrating the above equation and assuming P and T constant over the temperature range,
we obtain
P
P T
T

For T = 1C, we get

P 33.8 bar
