has a definite volume and shape solid
definite volume and indefinite shape liquid
indefinite shape and volume gas
a fixed amount of gas at a constant temperature, the volume of the gas increased as the gas' pressure decreases. likewise the volume of the gas decreases as the gas' pressure increases Boyle's law
The pressure of a gas increases as the temperature increases, if the volume of the gas does not change. The pressure decreases a the temperature decreases. Gay-Lussac's law
For a fixed amount of gas at a constant pressure, the volume of the gas increases as the gas' temperature increases. Likewise, the volume of the gas decreases as the gas' temperature decreases. Charles' law
the expand to fill their containers, the spread out easily, the mix with one another, low density, easy to compress behaviors of gases
solid to gas. energy is added sublimation
gas to liquid. energy is released condensation
liquid to gas. energy is added evaporation
liquid to solid. energy is released freezing
solid to liquid. energy is added. melting
what do the changes of state require. if it is added, the particles will move faster, and if it is removed, the particles move slower. ENERGY
able to separate back into separate mixtures physical property
not able to separate back into separate mixtures chemical property
Matter is made of atoms and molecules. Atoms and molecules act like tiny particles that are always in motion Kinetic theory
the most common state of matter in the UNIVERSE. 99% of all known matter (sun stars) plasma
the buoyant force on an object is a fluid on an upward force equals to the weight of the fluid that the object displaces. the greater the buoyant force, the more it will float Archimede's principle
if the pressure in a container is increased at any point, the pressure increases at all points by the same amount. pascal's principle
as the speed of a moving fluid increases, the pressure of the moving fluid decreases Bernoulli's principle
a liquid's resistance to flow. the stronger the attraction between a liquid's particles is, the more _______ the liquid is. viscosity/viscous
the amount of force exerted per unit area of a surface pressure
components are evenly distributed. the mixture is the same throughout. homogeneous mixtures
the substances is this are not evenly distributed. heterogeneous mixtures
able to be mixed miscible liquids
not able to be mixed together immiscible liquids
a matter that has a fixed composition and definite properties pure substances
a combination of substances that are not chemically combined mixtures
a group of atoms that are held together by chemical forces; a _______is the smallest unit of matter that can exist by itself and retain all of the substance's chemical properties. molecules
the smallest unit of an element that maintains the chemical properties of that element atoms
a substance that cannot be separated or broken down into simpler substances by chemical means elements
a substance made up of atoms of two or more different elements joined by chemical bonds compounds
shape and mass are examples some other ones are color, volume, and texture. physical properties
this describes how a substance changes into a new substance, either by combining with other elements or by breaking apart into new substances. chemical properties
the measure of average kinetic energy. is not determined by how much of a substance you have . the more kinetic energy the higher this is temperature
total kinetic energy of a substance's atoms thermal energy
Energy may change form during a chemical/physical change, but the total amount of energy remains the same. law of conservation of energy
