Term
Distillation
Definition
Method of purifying liquids which involves the evaprotion of the liquid followed by condensation of the gas.
Term
Solids
Definition
Solids have fixed shapes, fixed volumes, they cannot be compressed. their particles are held together strongly, with low energy the particles vibrate.
Term
Liquids
Definition
Liquids have no fixed shape, they fill the container from the bottom up. They have fixed volumes and can be compressed only very slightly. Their particles are held together very weakly. The liquids pareticles touch eachother and moved around randomly.
