2.18 A mole of argon is allowed to expand adiabatically and reversibly from a pressure of 10 bar and 298.15 K to 1 bar. What is the final temperature, and how much work is done on the argon?

Suppose we're interested in studying ligaments. In class, we have focused on Problem 1 work done by changes in volume, but our initial framework presented accommodates other forms of work as well. When a ligament is stretched, we may represent the work done on the system as follows: dw fdl - pdV || Here, fis the restoring force of the ligament that opposes stretching, and /is the length. The differential expression for the Gibb's free energy can be written as follows: dG = Vdp – SdT + fdl differential expression. dA. a) Write all Maxwell relations from the Gibb's free energy energy, b) Derive the differential expression for Helmholtz free
