characteristics that can only be measured or observed as matter transforms into a particular type of matter
a chemical substance that cannot be broken down into other substances by chemical reactions.
A chemical compound is a chemical substance composed of many identical molecules containing atoms from more than one chemical element held together by chemical bonds.

Physical change
Intensive properties
An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount.
a property that depends on the amount of matter in a sample. Mass and volume are examples of extensive properties.
a usually irreversible chemical reaction involving the rearrangement of the atoms of one or more substances
Chemical change
sugar, table salt, water, carbon dioxide, Sodium bicarbonate
a heterogeneous mixture in which the solid particles are spread throughout the liquid without dissolving in it.
muddy water, flour in water, sand particles in water, chalk in water,
A colloid is a mixture in which one substance consisting of microscopically dispersed insoluble particles is suspended throughout another substance.
mist, milk, jellies, whipped cream, pumic stone.
volume, mass, weight, boiling point.
Temperatures, density, color, melting and boiling point

Solutions
a special type of homogeneous mixture composed of two or more substances.
sugar in water and salt in water solutions, soda water
boiling an egg, baking a cake, milk growing sour, burning of paper or wood.
melting an ice cube, breaking a bottle, shredding paper, boiling water
chemical properties
flammability, toxicity, acidity, reactivity (many types), and heat of combustion
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance
A change in matter which does not alter the chemical properties of the matter
