Problem: A thermodynamic system has a large number of constituent parts that interact with each other obeying Newton's law of motion. Describe the approach you would use to model the properties of this system under these two different scenarios. Provide a justification for your answers and explain the role of the concept of equilibrium.
(i) Conducting an experiment where the duration of the experiment was short compared to the average time between interactions of the constituent parts.
(ii) Conducting an experiment where the duration of the experiment was long compared to the average time between interactions of the constituent parts.
