The three states of matter are SOLIDS, LIQUIDS AND GASES!
*If an object is a solid it means that it has definite shape, definite volume and definite mass
*If an object is a liquid it means it has definite mass and definite volume, but no definite shape
*If an object is a gas it means that it has no definite shape, no definite volume and no definite mass
Some examples of solids are apples, trees or pencils
Some examples of liquids are milk, juice or coffee
Some examples gases are sun, fire or fog.
Matter is made up of tiny particles(atoms and molecules). Particles of matter are in constant motion and are held together by very strong electric forces. Each substance has unique particles and temperature greatly affects the speed of the particles. So the higher the temperature the faster the speed of the particles and the lower the temperature the slower the speed of the particles.
The ways to identify matter are through their physical and chemical properties. The physical properties consist of:
*Color(green, blue, yellow, black, reddish brown)
*Odor(odorless, flowery, nauseating, spicy)
*Clarity(clear, cloudy, opaque)
*Luster(shiny, dull, glossy)
*Texture(how does it feel? fine, course, smooth, waxy)
*Brittleness(brittle or flexible)
*Malleability(can it be bent or folded into different shapes)
Chemical Properties consist of:
*iron rusts in moist air, gold does not
*hydrogen burns in oxygen, but nitrogen does not
*zinc reacts with acid, but glass does not
