what is the state of matter in which pressure is very low
Answers
States of matter are distinguished by changes within the properties of matter associated with external factors like pressure and temperature. States are usually distinguished by a discontinuity in one amongst those properties: say, raising the temperature of ice produces a transparent discontinuity at 0 °C or 32 °F as energy goes into a phase transition, rather than temperature increase. The classical states of matter are usually summarized as: solid, liquid, gas, and plasma. Within the 20th century, increased understanding of the more exotic properties of matter resulted within the identification of many additional states of matter, none of which are observed in normal conditions.

Low-energy states
Natural states
Solid: A solid holds a definite shape and volume without a container. The particles are held very close to each other.
Amorphous solid: A solid in which there is no far-range order of the positions of the atoms.
Crystalline solid: A solid in which atoms, molecules, or ions are packed in regular order.
Plastic crystal: A molecular solid with long-range positional order but with constituent molecules retaining rotational freedom.
Quasi-crystal: A solid in which the positions of the atoms have long-range order, but is not in a repeating pattern.
Liquid: A mostly non-compressible fluid. Able to conform to the shape of its container but retains a (nearly) constant volume independent of pressure.
Liquid crystal: Properties intermediate between liquids and crystals. Generally, able to flow like a liquid but exhibiting long-range order.
Non-Newtonian fluid: a fluid that does not follow Newton's law of viscosity.
Gas: A compressible fluid. Not only will a gas conform to the shape of its container but it will also expand to fill the container.
Plasma: Free charged particles, usually in equal numbers, such as ions and electrons. Unlike gases, plasma may self-generate magnetic fields and electric currents, and respond strongly and collectively to electromagnetic forces. Plasma is very uncommon on Earth (except for the ionosphere), although it is the most common state of matter in the universe.[1]
