States of Matter

Saige Peacock

Liquid

definition: composed of molecules that move freely among themselves but do not tend to separate like those of gases; neither gaseous nor solid

details:

-Molecules move more freely, but close together

-No definite shape (Takes shape of container) and has definite volume

-Medium kinetic energy


examples= milk, water, oil, honey

Gas

definition: substance possessing perfect molecular mobility and the property of indefinite expansion, as opposed to a solid or liquid

details:

-Molecules are far apart and can move freely

-No fixed volume and no definite shape

-High kinetic energy (more movement = more kinetic energy)

examples=helium and steam

Solid

definition: having three dimensions (length, breadth, and thickness), as a geometrical body or figure

details:

-Molecules packed closely together

-Low kinetic energy because the molecules don’t have room to move

-Definite volume

examples= a block, a ball, a sponge, a feather, a brick and a duck

Plasma

definition: hot ionized gas consisting of approximately equal numbers of positively charged ions and negatively charged electrons

details:

-Particles have extremely large amounts of energy

-Can be thought of as a gas consisting of electrons instead of atoms

-Most common phase of matter in the universe

examples= lightening, sun, and stars

Einstein-Bose Condensate

definition: a state of matter in which separate atoms or subatomic particles, cooled to near absolute zero

details:

-Einstein predicted this state of matter in the 1920’s

-It exists only at extremely low temperatures, -273°C (absolute zero : 0 K)

-Groups of atoms behave as though they are a single particle

examples= cold liquid helium, super fluids, neutron star
