It would increase and that's what I thought. But the book says that it is a system with a negative heat capacity. It's entropy vs. energy graph is concave-up. When you add energy, all the energy apparently goes into the potential energy and the particles in the system get farther apart and...
Homework Statement
For any system of particles held together by mutual attraction
U(potential) = -2 U(Kinetic)
Suppose you add energy to such a system and wait for it to equilibrate, does the total kinetic energy increase or decrease? ExplainHomework Equations
