Mapes (is that your name or a pseudonym?) Thanks for your help. By way of background, I am a 48 year old revising my university (college) physics - currently 1/2 way through 3rd year. I kept meticulous notes in my university years. This is one problem that has caused me trouble and that I...

What if you use dU = TdS - pdV + udN. Then u = the partial derivative of U w.r.t. N (WITH S FIXED). Mireno (aka "Morrie")

Can anyone help me. I am very confused about the chemical potential. In the following equation dU = TdS - pdV + u dN, where u is the chemical potential it seems to me that if you add particles to a system you are increasing the energy of that system, i.e. the chemical potential is...
