A gas is a sample of matter that conforms to the shape of a container in which it is held and acquires a uniform density inside the container, even in the presence of gravity and regardless of the amount of substance in the container..
Just so, what is gas and example?
Eleven elements-hydrogen, nitrogen, oxygen, fluorine, chlorine, helium, neon, argon, krypton, xenon, and radon-exist as a gas under standard pressure and temperature. Depending on the element, when the temperature or pressure is raised or lowered, then they will shift into another state. One example is pure oxygen.
Beside above, what is a gas definition for kids? Gases are air-like substances that can move around freely or they might flow to fit a container. They don't have a shape either. If they get out a container they spread very easily. Gases are all around us in the air that we breathe.
Beside this, how do you describe gas?
Gas particles spread out to fill a container evenly, unlike solids and liquids. Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids.
What are gases made of?
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).

Is fire a gas?
Fire is an oxidizing chemical reaction that releases heat and light. The actual flames that you see moving and glowing when something is burning are simply gas that is still reacting and giving off light. Plasmas are gases in which a good fraction of the molecules are ionized.Is the sun a gas?
The Sun is a huge, glowing sphere of hot gas. Most of this gas is hydrogen (about 70%) and helium (about 28%). Carbon, nitrogen and oxygen make up 1.5% and the other 0.5% is made up of small amounts of many other elements such as neon, iron, silicon, magnesium and sulfur.Is oxygen a gas?
Oxygen is an element that can be a solid, liquid or gas depending on its temperature and pressure. In the atmosphere it is found as a gas, more specifically, a diatomic gas.What are the types of gas?
Most gas stations offer three octane levels: regular (about 87), mid-grade (about 89) and premium (91 to 93). What is gas in science for kids?
Elemental gases are made up of two or more of the same atoms joined together. Hydrogen gas (H2) is an example an elemental gas. Compound gases contain a combination of different atoms. Carbon monoxide (CO) is an example of a compound gas.What are the 5 gases?

Is fire a gas or liquid?
Simply defined, fire is a chemical reaction in a mixture of incandescent gases, typically luminous with intense heat. All fires eventually burn themselves out, unlike solids, liquids, and gases, which can exist indefinitely in the same state.” Most of fire's energy output is in the form of heat.What is another word for gas in science?
You might hear the term "vapor." Vapor and gas mean the same thing. The word vapor is used to describe gases that are usually liquids at room temperature. Compounds such as carbon dioxide (CO2) are usually gases at room temperature. Scientists will rarely talk about carbon dioxide vapor.What are the 4 properties of gas?
There are four differently properties of gases that can be measured and that relate to each other through various laws we will discuss later in the unit. These properties are volume, temperature, amount and pressure. Each of these has a single letter commonly used to symbolize that property.Can gas be seen?
There are few gases that humans can see. Actually, gases aren't invisible: many are quite brightly coloured. Other gases in the atmosphere (particularly oxygen, carbon dioxide and water vapour) also absorb light, but at ultraviolet and infrared wavelengths that we can't see.What is the plural of gas?
Gases is the plural of gas, which is a noun meaning a substance that expands to fill any container. Gasses is a verb in the third-person present tense which carries a variety of meanings.What are gases used for?
Natural gases are used in the production of paper, glass, and clothing. Different types of gases are found in balloons (helium), soda (carbon dioxide), gas grills (propane), and lighters (butane). Hydrogen may one day even be used to fuel cars. These are only some of the many, many ways gases are used every day!What is the word for gas?
Word forms: gases, gasses, gassing, gassedlanguage note: The form gases is the plural of the noun. The form gasses is the third person singular of the verb. A gas is any substance that is neither liquid nor solid, for example oxygen or hydrogen.Whats is a solution?
A solution is a homogeneous type of mixture of two or more substances. A solution has two parts: a solute and a solvent. The solute is the substance that dissolves, and the solvent is the majority of the solution. Solutions can exist in different phases - solid, liquid, and gas.Can you see gas?
Some gases actually are visible (nitrogen dioxide for instance). The air is invisible, because its molecules don't absorb the visible light. One of the reasons why the eyes became sensitive in the "visible" spectrum is that air does not absorb there.Is water Vapour a gas?
Water vapor, water vapour or aqueous vapor is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice.How many gases are there?
How many gases are present in the air? The cocoon of gas that surrounds the planet is generally constant. Essentially three gases comprise 99% of the atmosphere: nitrogen, oxygen and argon, each with respective compositions of 78%, 20%, and 1%. The remaining 1% has a small variable.Are clouds a gas?
A cloud is a mass of water drops or ice crystals suspended in the atmosphere. Clouds form when water condenses in the sky. The condensation lets us see the water vapor. A cloud is a liquid, a solid, and a gas.Can a gas be squashed?
Because the particles are moving about, a gas will fill any container that it is put into. Because there is space between the particles, they can be squashed into a smaller volume when the gas is compressed. Look at the descriptions below.
