​Today's Agenda

Vocab of the Day

Mass

how much matter (atoms) is in an object

Vocab of the Day

Weight

how much force is being put on an object by gravity

Vocab of the Day

Density

measures how many atoms are packed into a certain space

Vocab of the Day

Volume

amount of space something takes up

Vocab of the Day

Conservation of mass

the amount of mass at the start of a REACTION will equal the amount of mass after the reaction

Vocab of the Day

Characteristic Property

Do not change based on how much of a substance is present. It can be used to identify a substance (Example: Density, Melting Point, Boiling Point, Freezing Point, Solubility)

Vocab of the Day

Phase of Matter/State of Matter

a way to describe the behavior of atoms in a substance (solids, liquids, gases)

Vocab of the Day

Contract

decrease in size, come closer together

Vocab of the Day

Expand

increase in size, move farther apart

Vocab of the Day

Pure Substance

a substance that is made from all the same types of atoms (synonyms: element)

Vocab of the Day

Solid

a state of matter that has particles that pack closely together and vibrate

Vocab of the Day

Liquid

a state of matter where the molecules have room to move around and flow

Vocab of the Day

Gas

a state of matter where the molecules fly around quickly, in all directions

Properties of Matter

• Physical properties are characteristics that can be OBSERVED or MEASURED without changing the composition of a substance.

• A CHEMICAL PROPERTY can only be observed when the substance is changing into another substance.

• Characteristic Properties DO NOT CHANGE depending on the amount of matter present.

Density Notes

• Density - measures how many atoms are packed into a certain space

• Amount of atoms in something - Mass

• Amount of space it takes up - Volume

• Density is a Physical Property

• Density = Mass/Volume

• Density is also a Characteristic Property so you can use it to identify substances

• Solids are the MOST dense, gases are the LEAST dense

• The density of water is 1 gram per cm². H2O (Water) is the only substance that is less dense when SOLID (Frozen), due to the way the atoms arrange themselves.

Solubility Notes

• Solubility is the ability of a substance to mix into another substance (liquid)

• Solute: the matter that gets dissolved into a SOLVENT.

• What a solute is dissolved in the solvent, the combination is called a SOLUTION.

• When a solvent (water) is heated, it INCREASES the solubility because the molecules are vibrating faster and SPREAD APART.

Atoms & Elements Notes

• Matter is anything that has mass and takes up space (has volume)

• Like matter, atoms have mass and occupy space

• There are more than 100 elements that combine in a multitude of ways that make up all of the living and nonliving things

• atoms are the "building blocks of matter".

• Elements are a pure substance made up of only ONE type of atom.

• Molecules are two or more atoms that bond together.

• Compounds are two or more atoms of different elements that bond together.

States of Matter Notes

• Solid atoms are TIGHTLY packed and do not move past each other. They VIBRATE in place

• Solids have a definite SHAPE, definite MASS and definite VOLUME.

• Liquid atoms are packed tightly together but not as tightly as SOLIDS. The atoms have enough room to FLOW or slide past each other.

• Liquids DO NOT have a definite shape. Liquids have a definite MASS. Liquids have a definite VOLUME.

• Gases: Atoms are NOT TIGHTLY packed together, and have so much ENERGY they slip past each other easily

• Gases DO NOT have a definite shape, gases DO NOT have a definite volume. Gases DO have a definite mass.

Phase Change Notes

• Boiling point - the temperature at which a substance turns from a LIQUID to a GAS.

• Melting Point - the temperature at which a substance turns from a SOLID to a LIQUID.

• Freezing Point - the temperature at which a substance turns from a LIQUID to a SOLID.
