Animals and plants require oxygen for respiration. Oxygen gas is colorless, odorless, and tasteless. Liquid and solid oxygen are pale blue. Oxygen also occurs in other colors, including red, pink, orange, and black.

The name oxygen comes from the Greek word “oxygenes” meaning “acid producer”. It was called this because early chemists thought that oxygen was necessary for all acids.

Air is an example of the type of matter known as gas. Other common forms of matter are solids and liquids. If you analyze air, it consists mostly of nitrogen and oxygen, with smaller amounts of several other gases, including argon, carbon dioxide, and neon.

The gas is colorless, odorless, and tasteless. The liquid and solid forms are a pale blue color and are strongly paramagnetic.

All matter is made from atoms. Every substance (oxygen, lead, silver, neon …) has a unique number of protons, neutrons, and electrons. Oxygen, for example, has 8 protons, 8 neutrons, and 8 electrons. Regardless of the type of molecule, matter normally exists as either a solid, a liquid, or a gas.

Smoke, smog, and laughing gas are matter. Energy, light, and sound, however, are not matter; ideas and emotions are also not matter. The mass of an object is the quantity of matter it contains.

On earth, solid, liquid, and gas are the most common states of matter. Not only is water the most common substance on earth, but it is also the only substance that commonly appears as a solid, a liquid, and a gas within the normal range of earth’s temperatures. Water is a unique substance because its molecules a.

Water illustrates the three states of matter: solid (ice), gas (steam), and liquid (water).

Steam that is saturated or superheated is invisible; however, “steam” often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapour condenses.

Examples of Liquids

• Water.
• Milk.
• Blood.
• Urine.
• Gasoline.
• Mercury (an element)
• Bromine (an element)
• Wine.

At room temperature (anywhere from zero degree centigrade to 100 degrees centigrade), water is found in a liquid state. Molecular water, therefore is a liquid at room temperature, a fact that is profoundly significant for all living things on this planet. Water is a Universal Solvent. Everything dissolves in water.

Liquids

• Oil in a puddle. Without a container, liquids form a pool or puddle. Oils are liquids that do not mix with water.
• Liquid metal. Mercury is a metal that is liquid at room temperature.
• Water in a glass. Liquids flow to fill the space around them.

Liquid facts for kids

• A liquid is a form of matter.
• Every small force makes a liquid change its shape by flowing.
• Fluids that flow slowly have a high viscosity.
• It is difficult to compress a liquid.
• Examples of liquid are water, oils and blood.

Gas Facts for Kids

• Like solids and liquids, gas is a common state of matter.
• Pure gases are made up of just one atom.
• Elemental gases are made up of two or more of the same atoms joined together.
• Compound gases contain a combination of different atoms.
• The air we breathe here on Earth is made up of different gases.

Surface tension, capillary action, and viscosity are unique properties of liquids that depend on the nature of intermolecular interactions. Surface tension is the energy required to increase the surface area of a liquid by a given amount. The stronger the intermolecular interactions, the greater the surface tension.

Facts about Gas Gas is essential to life on Earth. Oxygen helps produce energy in the human body, and carbon dioxide is used by plants for photosynthesis. Fire is formed from a combination of hot gases. Natural gases are lighter than air.

Water is, by far, the most common liquid on Earth. The density of a liquid is usually close to that of a solid, and much higher than in a gas.

Properties of Liquids

• Capillary Action.
• Cohesive and Adhesive Forces.
• Contact Angles.
• Surface Tension.
• Unusual Properties of Water.
• Vapor Pressure.
• Viscosity Viscosity is another type of bulk property defined as a liquid’s resistance to flow.
• Wetting Agents.

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.

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.

Liquid and gas states of matter can flow. The particles are further apart for both, which allows them space to move around easily.

The seven states of matter that I am investigating are Solids, Liquids, Gases, Ionized Plasma, Quark-Gluon Plasma, Bose-Einstein Condensate and Fermionic Condensate.

The properties of liquids include: Liquids can flow or be poured easily. They are not easy to hold. Liquids change their shape depending on the container they are in.

Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.
