What are the assumptions made in the gas model theory to simplify the model?
What are the assumptions made in the gas model theory to simplify the model?
Many molecules, moving rapidly and randomly, described by Newtonian mechanics, far apart with no pull, elastic collisions, forces only during collisions, small volume compared to gas volume.
