how many are states of matter?

The five phases of matter. There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates. In a solid, particles are packed tightly together so they don't move much.

A state is comprised of four elements: government, territory, population, and sovereignty. If one element is absent, it disqualifies the area from being called a state. However, a nation can be defined as a population who shares a similar culture and ideals.

Changes of state are physical changes in matter. They are reversible changes that do not change matter's chemical makeup or chemical properties. Processes involved in changes of state include melting, freezing, sublimation, deposition, condensation, and evaporation. Energy is always involved in changes of state.

Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around. ... Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume.

Matter in bulk is described by so-called state variables. These variables include volume V, pressure p, mass M, mass density ρ, thermal energy Eth and temperature T. If any one state variable is changed then the state of the system as a whole is changed. The fundamental building block of all matter is the atom.

In chemistry, the amount of substance in a given sample of matter is defined as the number of discrete atomic-scale particles in it divided by the Avogadro constant NA. In a truly atomistic view, the amount of substance is simply the number of particles that constitute the substance.

Everything is made of matter, so any object you can name consists of matter. Basically, if it takes up space and has mass, it's matter.

I. The Three States of Matter solid: definite shape, definite volume. liquid: indefinite shape, definite volume. gas: indefinite shape, indefinite volume. Indefinite shape means that the sample in question takes on the shape of the container.

Matter is made up of atoms and molecules. Molecules are atoms of more than two elements that are chemically bonded together. Each atom is a certain element that becomes a compound/molecule when bonded with other atoms. So matter is made up of one type of element or combinations of elements (atoms or molecules).

In physics, a state 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. ... Matter in the gaseous state has both variable volume and shape, adapting both to fit its container.

That reflects in the way how you count states: in classical statistics if you exchange positions of two atoms you count it as a different state. In quantum mechanics states with identical particles exchanged count as one state.

Three divisions of matter are recognized in science: masses, molecules and atoms. A Mass of matter is any portion of matter appreciable by the senses. A Molecule is the smallest particle of matter into which a body can be divided without losing its identity.

The state of matter with close spacing and indefinite shape is liquid.

Changes of state are physical changes in matter. They are reversible changes that do not change matter's chemical makeup or chemical properties. For example, when fog changes to water vapor, it is still water and can change back to liquid water again.

Classify matter as an element, compound, homogeneous mixture, or heterogeneous mixture with regard to its physical state and composition. Distinguish between mass and weight.
