Examples

  • In physics, this is described by the second law of thermodynamics, which says that systems will gain disorder or entropy over time.

  • It was the beginning of the science of thermodynamics, which concerns heat and movement.

  • And we will see what this does to the thermodynamics of the air.

  • Now, you might have thought the next concept in thermodynamics would be temperature.

  • Did you apply any principles of thermodynamics to your breakfast?

  • The second law of thermodynamics states that closed systems tend towards disorder.

  • The second law of thermodynamics says that in a closed system, everything eventually decays, rots, dies.

  • The second law of thermodynamics is usually summarized by saying entropy can't decrease.

  • Examples include Newton's Law of Gravity, Faraday's Law of Electromagnetism, and the Laws of Thermodynamics.

  • However, to understand why lift occurs, it is necessary to add the First Law of Thermodynamics (energy/mass cannot be created or destroyed) and Boyle's law.

8 5.4

A basic rule that explains how energy moves and changes in closed systems

4 7.0

Energy naturally spreads from hot places to cold ones, increasing disorder

1 4.5

Total energy in a place where nothing enters or leaves stays the same while it changes form

7.4

A law saying the disorder of a perfect crystal goes to zero at absolute zero

Study of how heat and energy behave in systems that have the same temperature

If two objects have the same temperature as a third object, they have the same temperature

Morphology

thermodynamics = dynamics (semi-transparent) = thermo + dynamics

The components 'thermo-' and 'dynamics' are recognizable, but the term names a specialized scientific field rather than a straightforward literal combination.

Etymology

Thermodynamics joins thermo- meaning 'heat' and dynamics meaning 'power or movement', and you can see the same parts in thermal (about heat) and dynamic (active or moving). So, thermodynamics is the study of how heat and energy move and change.
