Transcript of Matter
examples: book,desk,clock,table,chair,car,ice Gas - a state of matter that has no
definite shape or volume
examples:air,carbon dioxide Melting
-the change of state from a solid to a liquid
-example: ice heated turns into water Freezing - the change of state from a liquid to a solid example: when water gets really cold and turns to ice before Vaporization - the change of state from a liquid to a gas examples: when water get hot and changes into a gas before after water vapor evaporation - vaporization that takes place on the surface of a liquid example: a puddle getting smaller "or" drying up Boiling -the change of state from a liquid
to a gas below its surface as well as the surface example: water on a hot stove CONDENSATION -the opposite of vaporization example: breathing in the mirror -occurs when particles in a gas loose enough thermal energy to form a liquid Sublimation - the change on state from a solid to a gas -occurs when the surface particles of a solid gain enough energy that they form a gas example: dry ice ATOMS - The basic particle from which all elements are made example: an oxygen atom by:Nicole Vitullo LIQUID -a state of matter that has a definite volume
but no definite shape
examples: milk,water,juice,shampoo after ELEMENTS -A pure substance that can not be broken down into any other substances by chemical or physical means example: gold (Au) COMPOUND -a pure substance made of two or more elements chemically combined - a pure substance that cannot be broken down at all Ice is an
of a solid Heterogeneous Mixture -a mixture in which you can see the different parts example- salad VIDEO! YA A VIDEO example: Ionic Compound homogeneous mixture - a mixture in which you can't see the different parts example: salt water The difference between the two types of mixtures is the in a heterogeneous mixture you can see the different parts but in a homogeneous you can't. mass and volume mass- the amount of matter in a object volume- the amount of space a object takes up density= mass volume potential energy - energy that is stored up example: a bolder waiting at the top of a mountain Kinetic Energy - energy that is in motion example: a bolder rolling down a mountain Conservation of Energy Energy Transfers Motion Speed Direction - when energy is transferred from one form to another example: when a roller coaster is at the top of a hill it has potential energy but when it goes down the hill it changes to kinetic energy when a object is moving it is in motion when a object is in motion it has kinetic energy example: when a person is running he or she is in motion - how fast or slow something is speed = distance time - the way in which you are moving or facing examples: north,south,east,and west - to use less energy example: using solar power
