of definite shape and volume
, A state of matter that has no definite shape but has a definite volume because particles are free to move.
the regular repeating patterns that are formed in solids. These patterns create crystals ie., sugar,sand,salt,snow.Has a distinct charateristic melting point.
solids in which the particles are not arranged in regular pattern. Plastics,rubber,and glass are ex. No distinct melting point
a substance that flows.
the resistance of liquid to flow. High viscosity=slow flow ie molasses, Low viscosity=quick flow ie. water
Can change volume very easily. Particles spread apart, filling all space available. Gas has neither definite shape nor volume.
A measure of the average energy of motion of the particles of a substance
of the gas is the force of its outward push divided by the walls of the containers
the law that states that for a fixed amount of gas at a constant temperature, the volume of the gas increases as the pressure of the gas decreases and the volume of the gas decreases as the pressure of the gas increases
Charles found that when the temperature of a gas increases, its volume increases
diagrams that tell how two variables, or factors, are related
the total energy of motion in the particles of a substance
another form of energy that comes from the chemical bonds within matter
Change from liquid to solid
the phase change in which a substance changes from a liquid into a gas
process by which liquid water turns into a gas (water vapor) when heated
The process that occurs when vaporization takes place inside a liquid as well as on the surface.
the process by which molecules of water vapor in the air become liquid water
(chemistry) a change directly from the solid to the gaseous state without becoming liquid
another name for chemical change
alters the form of a substance, but does not change it to another substance.
substance is changed into a different substance with different properties.
law of conservation of energy
Energy changes from one form to another, but energy can never be lost.
