State Properties

Postby 004643111 » Sun Jan 10, 2016 8:32 pm

In the course reader on page 1, it states that the state properties are "U, P, V, T..." what do these stand for?

U is supposed to be E for energy. P is pressure, V is volume, and T is temperature.

Just to expand, U is the symbol associated with Internal Energy.

Because internal energy is a state property, the changes in internal energy are a function of the initial and final states (ΔU = UFINAL - UINITIAL (pg. 10 of CR)

If you read further on this page, you can see how formulas for ΔU can be formed.

Hope that helps!
