T vs P with V costant

[petrona]

who can give me a relationship between pressure and temperature of a liquid with costant volume?

Take a look at the post by 25362 in thread124-171158. Does that answer your question?

Good luck,

do you think that the relationship dP/dT = -alfa/k at costant V, deduced by 25362 post, is right? If so, T increase involves to P decrease, contrary to reality.
can you spend any words to make me understanding?
thanks

[(?V/?T)p]/[(?V/?P)t] doesn't equal ?P/?T as the two partial differentials are at different conditions. One is at constant pressure and the other one is at constant temperature.

This particular question was discussed atleast in 10 threads. For example,

thread391-220510
thread124-83163
thread135-85389

...and many if you can search.
