SCIENCE
Solution-type of mixture formed when I substance dissolves in another
Energy-The colder the phase, tends to have less energy
Freezing Point-Temperature where liquid turns to solid
Atomic Number-Number of protons in the nucleus of an atom
Matter-Has mass and takes up space
4 phases of matter-solid, liquid, gas, plasma
Mixture-Matter that consists of 2 or more substances mixed together but NOT chemically combined ex: salt, sugar
Atom-Smallest particle of an element that has the properties of a element
How do we measure mass-In grams
Mass number-Sum of protons and neutrons in its nucleus
Element-A substance that has only 1 kind of atom
Chemical Symbol-short way of representing elements
Melting Point-temputure where solid changes to a liquid
Freezing-change from liquid to solid
Condensation-change from gas to liquid (when drops get on glass)
Protons and Electrons-are equal to each other
Vaporization-change from liquid to gas
How do you change phases of matter-add or take away energy
