Question 2 Multiple Choice (Single Answer)

What is the difference between a microstate and a macrostate?

  1. A microstate is a complete description of the positions and momenta of all the particles in a system, while a macrostate is a description of the overall properties of the system, such as its temperature, pressure, and volume.
