matter Flashcards
Mass
.Measure of the amount of matter in an object
Matter
.Anything that has mass and takes up space
Volume
.Describes how much space a piece of matter takes up
Atom
.Smallest particle or part of matter
Molecule
.Two or more atoms joined together
Nucleus
Middle of atom containing protons and neutrons
Liquid
.Liquids have indefinite shape and definite volume, tightly packed but far enough apart to slide over one another
Gas
.Indefinite shape and volume, part les far apart and move freely
Plasma
.Particles that move freely, don’t have a shape and are electrically charged
Element
.Matter that is made up of only one kind of atom
Proton
Positively charged particle in an atomic nucleus
Neutron
Neutrally or not charged practical in atomic nucleus.
Electron
Negatively charged part of the atom surrounding the atomic nucleus
Element
.Matter that is made of only one kind of atom
Atomic number
.Number of protons in nucleus
Density
.Tells how massive something is for it’s size
Buoyancy
.An object’s ability to float
Combustible
.A matters ability to catch on fire
Chemical reaction
Two elements turn into another substances
Physical reaction
.Type of change from one form to another (water to ice)
Conservation of matter
.Chemical changes don’t make new matter
Exothermic reaction
.Chemical reaction in which heat is released
Endothermic reaction
.Chemical reaction in which heat is absorbed
Saturated
.When the solvent won’t absorb anymore solute
Suspension
.Particles that aren’t dissolved but can be easily seen
Solvent
.The water that we dissolved the sugar into
Solubility
A solutions ability to dissolve a solute or powder
Four states of matter
Solid, liquid, gas, plasma
Solid
Particles that have a set shape and volume, tightly packed and vibrating
Reason atoms bond together
