For My Science Class

Solid A state of matter (particles that don't move,they are so close together that when they try to move they just calmly vibrate)
Liquid A state of matter (particles that move and are a far distance from each other)
Gas A state of matter (particles that are moving really fast,bouncing off the walls, and becomes it's form when water gets hot)
Plasma An ionized gas consisting of positive ions and free electrons in proportions resulting in more or less no overall electric charge, typically at low pressures or at very high temperatures
Colloid A homogeneous, noncrystalline substance consisting of large molecules or ultra microscopic particles of one substance dispersed through a second substance
Phase change When a substance changes from one state, or phase, of matter to another we say that it has undergone a change of state, or we say that it has undergone a change of phase
