Chemistry - Matter

matter

Anything that takes up space, has volume, density, and mass

Mass

how much matter is in an object

Weight

A measure of the force of gravity on an object

States of matter

liquid, solid, gas, plasma

liquid

water, juice, milk

solid

wood, ice, pencil

gas

oxygen and water vapor

plasma

lightning, sun, stars

intensive property

does NOT depend on how much matter is in an object to describe it

extensive property

DOES depends on how much matter is in an object in order to describe it

intensive property example

color, temperature

extensive property example

weight, length, mass

chemical property

indicates how a substance reacts with something else, matter will be changed into a new substance after the reaction

physical property

a characteristic that can be observed or measured without changing the identity of the substance

chemical properties examples

flammability, toxicity, reactivity

physical properties examples

color, smell, density, boiling point,

physical change

a change of matter from one form to another without a change in chemical properties

chemical change

A change that occurs when one or more substances change into new substances with different properties.

physical change examples

cutting string, crumpling paper, melting ice, evaporating water

Examples of chemical change

Rusting of iron nail, Baking a cake

Law of Conservation of Matter

matter cannot be created or destroyed

mass of reactants = mass of products

The reactants that went into the making of the product have the same mass as the actual product once its made since matter cannot be destroyed or created.
