solids
definite shape, definite volume
liquids
indefinite shape, definite volume
gases
indefinite shape, indefinite volume
plasma
high-energy matter consisting of positive and negatively charged particles
plasma 
it is the most common matter in space
qualitatively
state of matter
color
texture
using senses
quantitatively
mass
volume
density
mass 
amount of matter in an object. (g)
volume
amount of space the matter occupies. (L)
density
mass per unit volume of a substance. (g/mL)
surface tension
the uneven forces acting on the particles of a surface of a liquid
viscosity 
is a measurement of a liquid's resistance to flow
viscosity
the greater the viscosity, the thicker it is and the greater it's resistance to flow
vapor 
the gas state of a substance that is normally a solid or a liquid at room temperature
diamond
crystalline solid, has structure
charcoal
amorphous solid, indefinite structure
kinetic molecular theory
all molecules, regardless of their masses, have the same average kinetic energy at the same temperature.
atoms 
gases are composed of atoms or molecules that are widely separated from one another.
speed
gas molecules move at very high speeds, travelling in straight paths at different directions
collision
gas molecules collide with one another with the sides of the container.
kinetic
the average kinetic energy of the molecules is determined by gas temperatures
ideal gases
one in which intermolecular forces are negligible and gas molecules occupy a negligible volume
real gases 
almost as ideal gases at ordinary temperatures and pressures
pressure
amount of force applied per unit of area
ideal gases
intermolecular forces are negligible and gas molecules occupy a negligible volume
real gases 
almost as ideal gases at ordinary temperatures and pressures
pressure
the amount of force applied per unit of area. the higher the volume, the lesser the pressure of the container.
