If you say that a situation is a matter of a particular thing, you mean that that is the most important thing to be done or considered when you are involved in the situation or explaining it. …

The definition of matter is what something is made of, what all physical things are made of, or something important or a problem. An example of matter is a dining table made of wood. An example of matter is everything we see being made of particles of elements and atoms.

A common or traditional definition of matter is “anything that has mass and volume (occupies space)”. For example, a car would be said to be made of matter, as it has mass and volume (occupies space).

Matter is anything that has mass and takes up space. At a minimum, matter requires at least one subatomic particle, although most matter consists of atoms. The word matter is sometimes used to refer to a pure substance.

The three states of matter are: Solids: The strong bonds between molecules make solids rigid and very difficult to deform. Liquids: The relatively weak bonds between molecules allow liquids to be deformed without effort.

Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.

We can see that matter around us exists in three different states– solid, liquid and gas. These states of matter arise due to the variation in the characteristics of the particles of matter.

Liquids flow because the intermolecular forces between molecules are weak enough to allow the molecules to move around relative to one another. In liquids, the intermolecular forces can shift between molecules and allow them to move past one another and flow.

Solids, liquids and gases are different mainly because of their lattice arrangements and the cohesive forces between the molecules. The cohesive forces between their molecules are also very weak. This gives gases their property to flow and compressibility.

Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.

Key Takeaways: Examples of Solids, Liquids, and Gases A solid has a defined shape and volume. A common example is ice. A liquid has a defined volume, but can change state. An example is liquid water.

Deposition refers to the process in which a gas changes directly to a solid without going through the liquid state. For example, when warm moist air inside a house comes into contact with a freezing cold windowpane, water vapor in the air changes to tiny ice crystals.

Three states of matter exist – solid, liquid, and gas. Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.

Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either. The change from solid to liquid usually does not significantly change the volume of a substance.

Gas – In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other. In most cases, there are essentially no attractive forces between particles.

The particles of solids are tightly bound to each other so their positions are set and compressed, therefore they don’t have the ability to flow. On the other hand, liquids and gases are the opposite, therefore allowing their molecules to move and giving them the ability to flow.

Fluids display properties such as: not resisting deformation or resisting it only lightly ( viscosity ), and the ability to flow (also described as the ability to take on the shape of the container). Ideal fluids can only be subjected to normal, compressive stress which is called pressure.

1 : the quality or state of being fluid. 2 : the physical property of a substance that enables it to flow.

All liquids show the following characteristics:

• Liquids are almost incompressible. In liquids molecules are pretty close to each other.
• Liquids have fixed volume but no fixed shape.
• Liquids flow from higher to lower level.
• Liquids have their boiling points above room temperature, under normal conditions.

A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.

Liquids may be divided into two general categories: pure liquids and liquid mixtures. On Earth, water is the most abundant liquid, although much of the water with which organisms come into contact is not in pure form but is a mixture in which various substances are dissolved.

Liquid water is wet and fluid. This is the form of water with which we are most familiar. We use liquid water in many ways, including washing and drinking. Water as a gas—vapor is always present in the air around us.
