Configurational Entropy

Ludwig Boltzmann killed himself so that we could do thermodynamics by enumerating the states of a system. Learn to count, the most important skill in statistical mechanics.

Configurational entropy (qualitative)


In the above circuit, the voltage across the resistor \( R = 13 \ \Omega \) is \( V = 0 \text{ V}. \) If the voltage \( V \) is suddenly increased to \( V' = 13 \text{ V},\) what has happened to the entropy of the system of electrons in the circuit?

If a warm object contacts a cold object, in which direction will the heat flow?

\( 100 \) air particles are flying around a room. Suddenly, all the particles are moved to one side of the room. What has happened to the entropy of the system?

If we put a cup of water into a freezer, what will happen to its entropy?

If ice cream is melted in a warm room, what happens to the entropy of the system?
