Chapter 1 Intro To Matter Sections 1,2,&3

Weight

Weight

a measurement of of the force of gravity acting upon something

Volume

is the amount of space that matter occupies

Physical changes

________- a change that does not make the material into another substance.

Mass

the measurement of how much matter something contains

Chemical change (chemical reaction)

a change in matter that produces new substances

ratio of elements

A formula shows the ________ in a compound.

to calculate density

mass and volume are required, d=m/v

gasses

Matter has three states- solids liquids and ________.

Chemistry

________: the study of properties of matter and how matter changes.

Daltons ideas

________ form the basis of our understanding of atoms.

constant ratio

The masses of the elements in a compound are always in a(n) ________.

SI

________ uses kilograms grams and other metric units.

Atoms

________ are rearranged in new combinations even though it has same elements as original substance.

blocks of matter

Substances are building ________- atoms (Elements)

Compound

________: substance made of two or more elements chemically combined in a specific ratio.

Dalton

________ proposed an atomic theory.

a mixture

made of two or more substances, elements, compounds, or both that are combined in the same place but are not chemically combined into a new substance

samples of a substance

All ________ have the same for all samples of that substance.

Mass

________ is the amount of matter someone or thing has while weight is the force gravity has on you.

EQ

What properties help you sort matter

Matter

The stuff that makes up everything in the universe

Compound

substance made of two or more elements chemically combined in a specific ratio

Matter has three states

solids liquids and gasses

Several properties of matter that help you identify an unknown substance

flammability, color, texture, hardness, shape, temperature

building blocks of matter

atoms (Elements)

Explain the difference between a physical change and a chemical change

Physical is same substances while chemical makes new substances

How does chemical formula differ from a symbol

chemical formula is made of multiple elements and a symbol is just one element
