Covers the study of (primarily homogeneous) macroscopic systems from a heat/energy/entropy point of view. Consider also using the tag: [statistical-mechanics].
When to Use This Tag
thermodynamics should be used if your question discusses the time-evolution of a mostly homogeneous, macroscopic system – for example, a cold bottle of water in a warm bathtub. You can combine this tag with statistical-mechanics for a microscopic derivation of thermodynamical laws and maybe with the other ‘macroscopic’ tags, such as cosmology or gravity, depending on your problem. Tagging a question as both thermodynamics and quantum-mechanics usually makes no sense unless in the context of thermal-radiation.
