In physics, a state of matter or phase of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma.
Bromine in both liquid and gas state, encased inside acrylic in solid state
Helium's orange glow in its plasma state
Artificial plasma produced in air by a Jacob's Ladder. The extremely strong potential difference between the two rods ionize particles in the air, creating a plasma.
SBS block copolymer seen with transmission electron microscopy (TEM)
Liquid is a state of matter with a definite volume but no fixed shape. When confined in a container and subject to a force such as gravity, liquids will adapt to the internal shape of the container in
State of matter
…state of matter or phase of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma. Different states are distinguished by the ways the component particles (atoms, molecules, ions and electrons) are arranged, and how…
The formation of a spherical droplet of liquid water minimizes the surface area, which is the natural result of surface tension in liquids.
Cavitation in water from a boat propeller
A lava lamp contains two immiscible liquids (a molten wax and a watery solution) which add movement due to convection. In addition to the top surface, surfaces also form between the liquids, requiring a tension breaker to recombine the wax droplets at the bottom.
