What is the difference between a state and a microstate of a system? check all that apply. check all that apply. a thermodynamic state is a set of conditions, usually temperature, volume, and number of moles, that defines the properties of a bulk material. a microstate is a single possibility for all the positions and kinetic energies of all the molecules in a sample. a thermodynamic state is a single possible arrangement of the positions and kinetic energies of the molecules. a thermodynamic state is a set of conditions, usually temperature and pressure, that defines the properties of a bulk material. a microstate is a snapshot of positions and speeds at a particular instant.
