Food molecules and waste material
Most large insoluble molecules get broken down in the digestive system to small (simpler) soluble molecules.
Large molecules use exocytosis =D

solid
density
Is watr
molecules are packed together and make volume density.
No the molecules are all packed altogether tightly
mean free path
Solids, usually.
in solids molecules are tightly packed in liquid molecules are not so tightly packed whereas in gas they are free to move
Compression
Compression
Rarefaction
How close together the molecules (particles) are in a substance/material. Solids are closely packed, liquids are loosely packed, and gas are very loose, freely moving molecules.
