Lesson 1
Matter: anything that has mass and takes up space.
Property: The characteristics of something.
Physical Property: Traits of a substance that can be observed without changing what it is.
Intensive Properties: A subsection of physical properties, independent of how much matter there is.
Extensive Properties: The dependent on matter subsection of physical properties.
Lesson 2
Chemical Property: The property to change into another substance.
Metals react with oxygen creating rust on the metal.
Lesson 3
Physical States of Matter: There are 3 physical states of matter, solids, liquids, and gases.
Solid: A solid is one of the physical states of matter, its atoms are packed tightly together.
Liquid: A liquid is another one of the physical states of matter, its atoms are loosely together.
Gas: A gas is the last type of the physical state of matter, its atoms aren’t held together at all.
Phase Change: A phase change is where atoms change from one state of matter to another.
Melting: Melting is the change in heat that causes the phase to start changing.
Freezing: Freezing is where the temperature starts going down, causing the phase to change.
Vaporization: When the heat comes up so much that the state of matter turns into a gas.
Condensation: When the vapor cools down it starts to condensate.
Physical Changes: A physical change is where a phase change happens, but its identity as an object stays the same.
