Law of thermodynamics
The laws of thermodynamics are a set of scientific laws which define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium.

System context
First law of thermodynamicsis part ofLaw of thermodynamicsEstablished
Open First law of thermodynamics →
first law of thermodynamics is part of law of thermodynamics.
Mechanism: The first law is thermodynamics' conservation rule: energy is never created or destroyed, only converted between heat, work and internal energy.

Second law of thermodynamicsis part ofLaw of thermodynamicsEstablished
Open Second law of thermodynamics →
second law of thermodynamics is part of law of thermodynamics.
Mechanism: The second law is thermodynamics' arrow of time: in any real process, total entropy — disorder — increases, so heat flows only from hot to cold.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Currently dark in the atlas: no key date stored · 3 of 3 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Structural neighbourhood: 3 → 15 → 71 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.
All 3 of its relationships stay within its own discipline — a field-specific concept in the current atlas.
structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
