Matter Study Guide

define matter

anything that takes up space

does the image show solid, liquid, or gas

solid

does the image show solid, liquid, or gas

liquid

does the image show solid, liquid, or gas

gas

list four indicators of chemical change

bubbles (creation of gas), temperature change, color change, production of an odor

list four types of matter

atom/element, molecule/compound, homogeneous mixture, heterogeneous mixture

list four states of matter

solid, liquid, gas, plasma

list properties of solids

particles do not move much, definite shape(doesn't change), not much empty space

list properties of liquid

particles slide around, not much empty space, takes on the shape of its container

list properties of gas

particles move a lot, a lot of empty space, very compressible, takes on the shape of its container

list properties of plasma

adds heat to a gas, releases electrons, charged atoms

new substance means

different molecules present

define physical property

observation of a substance without changing it

list examples of physical property

smell, color, density, texture, boiling point, melting point

define physical change

no new substance made, same molecules present before and after, easily reversable

list examples of physical change

change of state, change of shape, change of size, making kool aid

define chemical property

ability of a substance to have a reaction

list examples of chemical property

ability for paper to burn in air, ability for iron to rust

define chemical change

a new substance is made, different molecules present after the reaction

list examples of chemical change

bubbles, heat released, burning, cooking,

define pure substances

has a set composition, same globally, cannot be broken down by physical changes

define atoms

smallest particles

define compounds/molecules

made of two or more atoms (ex: H2O)

define mixtures

has several pure substances mixed together, can be broken down by physical changes

what are the two types of mixtures

homogeneous mixture, heterogeneous mixture

define homogeneous mixture

consistent composition (ex: milk, lotion, salt water)

define heterogeneous mixture

irregular composition (ex: chocolate chip cookies, salad, granite)
