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

Explanation:

A state of a system in thermodynamics give the properties that a material is been made up, these properties could be pressure, temperature, volumes and others , they are been called thermodynamic property

Microstates helps us to know how molecules is been arranged in single instant. Kinetics energy as well as position of molecules in a particular substance can be known in single instant.

b is the correct answer

mark me brainliest and hope this

c. 4.54 x 10–12 j happens to be correct
