Title: thermodynamic numerical
Post by: rabea on March 31, 2005, 03:26:33 pm
hey guys,
this is someones question and i dont know the answer so could anyone of u plz answer it for me??ASAP.thanx in advance. :)

i was trying to solve some thermodynamic numericals for my test next week and i couldn't solve this one.
A mass of liquid with volume V completely turns into a gas of volume V' at a constant external pressure P and temperature T.
The latent heat of vaporisation is L for the given mass.
what will be the change in the internal energy of the system??

a)PV'-PV

b)L-PV'+PV

c)zero

d)L+PV'-PV
Kaveri.

take care
