For acetone, find;
o
(a) The value of (эP/эT)V at 20 C and 1 bar
o
(b) The pressure generated by heating at constant V from 20 C
and 1 bar to 30oC.
(c)
The change in volume for a change from 20oC and 1 bar to 0oC
and 10 bar.
o
(d) The saturate liquid phase molar volume for at 30 C (Hint: Obtain
critical values form web sources).
For Liquid acetone at 20oC and 1 bar,
ɴ = 1.487 x 10-3 oC-1 , ʃ = 62 x 10-6 bar-1 and V = 1.287 cm3 g-1
