Physical Change
A change in the form or appearance of matter that does not change it into a different kind of matter
Change Of State
A physical change in one kind of matter that describes how it reacts with other kind matter
Melting point
The teperature at which a solid melts, or becomes a liquid
Boiling point
The teperature at which a liquid becomes a gass
Evaporate
To change from a liquid to a gas at a temperature below the boilling point
Condense
To change from a gas to a liquid
Mixture
A blend of two or more Materials or substances that have been mixed together physically without being combined cemically
Solution
A type of mixture in which particles of one substance have dissolved in another substance and are spread evenly throught it
Solute
The substance that dissolves in a solvent to form a solution
Solvent
The substance in which a solute dissolves to form a solution
Solubility
How much solute will dissolve in a certain amount of solvent at a certain temperature
Suspension
A type of mixture in which particles of one substance are floating in another substance and are not spread evenly throughout it
Colloid
A type of mixture that has properties in between those of a solution and a suspension
Chemical Change
A change in one kind of matter that results in the formation of one or more chemically different kinds of matter
Matter
Anything that takes up space and has mass
Physical Property
Characteristic of a substance that can be observed or measured
Mass
A measure of the amount of matter in an object
Balance
A tool for measuring mass
Volume
A measure of the amount of space an object takes up
Density
A measure of the amount of mass per unit volume of a substance
States of Matter
The physical form of a substance
Solid
The state of matter that has a definet volume and shape
Liquid
The state of matter that has a definet volume but no definet shape
Gas
The state of matter that has no definet volume or shape
Chemical Property
A property of a substance that is made up of the atoms of more than one element and that forms as the result of a chemical reaction
Atoms
A tiny building block of matter; the smallest unit of an element that has the properties of that element
Nucleus
The central part of an atom, made up of protons and neutrons
Protons
A tiny part of an atom with a positive charge that is located in the nucleus of an atom
Neutrons
A tiny part of an atom with no charge that is located in the nucleus of an atom
Electrons
A tiny part of an atom with a negative charge that moves in the space around the nucleus
Element
A substance that cannot be broken down chemically into simpler substances and is made up of only one type of atom
Periodic Table
A chart in which elements are arranged according to their chemical properties
Metal
An element that is a solid, it's usually shiny, and is a good conductor of heat and electricity
Molecule
The smallest unit of a substance that can exist alone and still have the properties of that substance
Compound
A substance that is made up of the atoms of more than one element that forms as the result of a chemical reaction
Automatic Number
The number of protons in the nucleus of an atom, then determines its place in the periodic table.
What makes each element different?
The number of protons in its nucleus
