fractions with the lowest boiling points generally contain the smallest molecules, which have fewer electrons and weaker London Forces
The diffence between chemical and physical is that ones chemical and ones physical!!
a physical change is reversible but a chemical change is irreversible
I'm not sure what the Chemical difference in property is, but the physical difference would be that ash is powdery and wood is solid.
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
An element is by itself while a compound is two or more.
Joseph Kagan has written: 'Fractionation of starch, and an examination of some of the physical and chemical properties of the fractions'
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.

A physical change is reversible, a chemical change is not.

a physical change is reversible but a chemical change is irreversible
a physical change is reversible but a chemical change is irreversible
The difference is that chemical equilibrium is the equilibrium of products and reactants in a reaction while physical equilibrium is the equilibrium of the physical states of the same substance.

a physical reaction you can see and a chemical is the molecules changing inside the object
You can tell the difference by knowing that a physical property changes shape and that a chemical property changes the substance.
