Entropy of Gases and Gravity

The video explores the second law of thermodynamics, focusing on entropy as a measure of disorder. It illustrates this with examples of gas spreading in a box and stars clumping due to gravity. The discussion extends to the early universe, where both gravitational and other physical processes contribute to the observed uniformity and thermal equilibrium.

Describe the difference between a uniform state and a non-uniform state in relation to entropy.

What is the significance of thermal equilibrium in the context of the early universe?
