D.4.6 (Thermodynamics of gasses)
D.4.6.1 Compressed gas expanding against the atmosphere is in free expansion.
[Beall (94), C1a: 17%]
D.18.104.22.168 Compressed gas expanding against the atmosphere does no work
undergoes no temperature change.
D.4.6.2 Compressed gas expanding against the atmosphere becomes cold, like a
CO2 fire extinguisher. [Beall (94), C1a]64
D.4.6.3 Compressed gas expanding against the atmosphere fails to come into
equilibrium with the atmosphere. [Beall (94), C1a: 11%]
D.4.6.4 All ideal gas processes are isothermal. [Beall (94), C1a]
D.4.6.5 Gasses at higher pressure have higher temperatures because their
molecules collide more often. (* A.7) [Beall (94), C1a: 17%]
D.4.6.6 (Mean distance between particles and mean kinetic energy of particles
conflated) (* D.4.6) [Rozier (1991), inferred.]
D.22.214.171.124 In solids, such as glass and plastics, molecules are squashed against
each other and cannot move. [French textbook, in Rozier (91)]
D.126.96.36.199 When cooling down a liquid, particles become motionless without any
order; it is an amorphic solid.
[French printed university material, in Rozier (91)]
D.188.8.131.52 Particles need more room to move faster.
[French popular science book, in Rozier (91).]
D.184.108.40.206 The same amount of heat transferred to the same number of particles
of a perfect gas will produce less temperature increase if they are in a
larger volume. [Rozier (91), C: 37%]
