Heat and Cold

All terrestrial bodies have many pores through which these smaller particles can pass through.
- But several have pores so narrow or constricted that they do not accept the larger particles.
- These usually feel the coldest when touched or even when approached.
Marble and metals feel colder than wood because their pores do not easily accept the less subtle particles of the fire-aether.
- Ice is colder than metals because its pores accept the fire-aether even less than those of metals.
This is because:
- Heat is the small particles of the bodies that we touch being agitated more strongly than usual.
- Cold is them being agitated less than usual.*
Superphysics Note
This agitation can be caused by the small particles of the fire-aether.
- This agitation transfers to the small filaments of our nerves that are the organs of touch.
The States of Matter: Water and Ice
The particles of hard bodies are like intertwined branches.
- This fire-aether does not separate those particles in the same way that it does those of water and liquids.
But it nonetheless agitates and makes them tremble according to:
- how strong its movement is
- how large its particles are
This is like how the wind can agitate all the branches of shrubs that form a hedge without removing them from their places.
There is a proportion between:
- the force of this fire-aether
- the resistance of the particles of bodies
Ice turns into water when it is more agitated.
This agitation can come from the larger fire-aether particles that are near the surface of the earth [at sea level]. These larger fire-aether particles then have the force to:
- agitate and move the ice particles separately from one another
- bend most of the small particles of the water among which it slips, thus making it liquid.
Water turns into ice when it becomes less agitated.
This lesser agitation can come from the subtler fire-aether, such as those that are in the atmosphere, or during winter.
- The fire-aether then does not have enough force to bend and agitate the water particles.
- This causes the water to remain confusedly joined and laid one on top of the other, creating a hard body as ice.
The difference between water and ice is like the difference between eels:
- floating in a fisherman’s boat full of holes through which the river water passes and agitates them, and
- the same eels dry and stiff with cold on the shore.
Water only freezes when the fire-aether between its particles is more subtle than usual.
It follows that the pores of such ice are arranged in such a way that they cannot accept the larger and less subtle fire-aether.
Thus, the ice is always very cold, even when kept until summer. It retains its hardness without gradually softening like wax, because the heat only penetrates inside as the surface becomes liquid.
