Unformatted text preview: happens to T, P, V) What sign does W have? Calculating Work We can plot PV diagrams. The area under the curve is W. W = F Δ x F = PA W = P ( A Δ x )= P Δ V Fixed Quantities Fixed Quantities W = n RT ln ( V f V i ) Fixed Quantities P ∝ 1 V γ Δ U =− W Example: Here W>0. What can we say about T? The Path Makes a Difference Reversibility Reversible: When a process is reversed, the final state (of the system and the environment) is exactly the same as the initial state. Irreversible: There is no way to return the system and its environment to the original state 2 nd Law Heat flows spontaneously from a warm body to a colder one. It is not possible for heat to flow spontaneously from a cold body to a warmer one....
