Question 2
In thermodynamics, interactions between large ensembles of objects are studied and categorized. Central to this are the concepts of the
thermodynamic system and its surroundings. A system is composed of particles, whose average motions define its properties, and those
properties are in turn related to one another through equations of state. Properties can be combined to express internal energy and
thermodynamic potentials, which are useful for determining conditions for equilibrium and spontaneous processes.
