Particles tend to move from higher chemical potential to lower chemical potential because this reduces the free energy. In this way, chemical potential is a generalization of "potentials" in physics such as gravitational potential.When a ball rolls down a hill, it is moving from a higher gravitational potential (higher internal energy thus higher potential … can i order from missoni websiteWebw= -Pext (delta V). You need the negative in front because when work is done "on the system" (which is positive), delta V (Vfinal-Vinitial) is negative (the ballon is compressed). So the two negatives make the whole term for work positive. Side note: remember that external pressure (Pext) is considered constant. can i order from kmart onlinehttp://article.sapub.org/10.5923.j.pc.20240703.02.html five fathoms tattooWebFirst Law of Thermodynamics The first law of thermodynamics is the application of the conservation of energy principle to heat and thermodynamic processes: .
