Looking for a Gas The word vapor is used to describe gases that are usually liquids at room temperature. Good examples of these types of liquids include water (H2O) and mercury (Hg). They get the vapor title when they are in a gaseous phase. You will probably hear the term “water vapor” which means water in a gas state.

How much gas is in the air? Air is a mixture of different gases (nitrogen, oxygen, water vapor, argon, carbon dioxide, etc.) but all are gases, so air is fully 'gaseous'. Yes, it is one of the 6 noble gases. It is somthing used for lights in shops.   As a gas, nothing ... Neon gas is a noble gas / inert gas at STP. Technically, air is a gas.

- When they melt, the resulting liquid conforms to the shape of its container. Gases expand to fill their containers. There are two reasons for studying gases before liquids or solids. First, the behavior of gases is easier to describe because most of the properties of gases do not depend on the identity of the gas.

- A gaseous substance is an object (such as steam) that has the propeties of a gas. The properties of a gas. Steam is an example-the particles are widely spread throughout the … substance and have plenty of room to move about. Gas is, in simpler terms, a fluid with no shape, volume of mass.hemist for uranium nuclear fuels. Examples at standard conditions: carbon dioxide, sulfur dioxide, nitrogen dioxide, methane, propane, hydrofluoric acid, hydrochloric acid, ammonia, etc.

- Gases become liquids when they have less space to occupy or when the temperature is cool enough for that substance to be a liquid. Take water as an example. When the temperatu … re is hot enough, it is steam. As the temperature cools, the molecules loose energy and begin sticking together forming liquid water.

Looking for a Gas 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. Good examples of these types of liquids include water (H2O) and mercury (Hg). They get the vapor title when they are in a gaseous phase. You will probably hear the term “water vapor” which means water in a gas state. Compounds such as carbon dioxide (CO2) are usually gases at room temperature.

CONTENTS Within the lower atmosphere, however, air remains remarkably uniform in composition, as a result of efficient recycling processes and turbulent mixing in the atmosphere. Atmospheric Gases. There are a number of atmospheric gases which make up air. The main gases are nitrogen and oxygen, which make up 78% and 21% of the volume of air respectively. Oxygen is utilised primarily by animals, including humans, but also to a small degree by plants, in the process of respiration (the metabolism of food products to generate energy). The remaining 1% of the atmospheric gases is made up of trace gases. These include the noble gases, very inert or unreactive gases, of which the most abundant is argon. Other noble gases include neon, helium ...

- Lots of things that are gases at room temperature can be frozen into liquids or solids at cold temperatures. Ice is just water frozen into a solid. Even though dry ice is called ice, it's not. Dry ice is actually a gas at room temperature - carbon dioxide - frozen into a solid at about -110 degrees.

Ideal gases vs. Real gases An ideal gas is a theoretical gas which perfectly fits into the equation PV= nRT. An ideal gas is different from a real gas in many ways. An ideal gases’ mass can be disregarded in the equation because it has none; this is because an ideal gas is said to be a particle and particles do not have any mass. Ideal gases obtain no volume unlike real gases which obtain small volumes.

What is the difference between solid, liquid and gas? Chemistry is Life. The mobile/laptop you used to type out this questions has definite shape and definite volume, so it's called a 'Solid'. The air you breathe, it has a definite volume but no definite shape, it's called 'Gas'. The water you drink, it has a definite volume, but no definite shape, though it can take the shape of container it is stored in. It is called a 'Liquid'. These are collectively called 'States of Matter'. That was just superficial stuff. Besides these, the most abundant matter in the universe, Plasma.

How many states are there in the world? Gas particles have enough kinetic energy to overcome intermolecular forces that hold solids and liquids together, thus a gas has no definite volume and no definite shape. Plasma. Plasma is not a common state of matter here on Earth, but may be the most common state of matter in the universe. Plasma consists of highly charged particles with extremely high kinetic energy.

Gas 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). A gas mixture would contain a variety of pure gases much like the air. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles.

Breathing gas A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common, and only natural, breathing gas. But other mixtures of gases, or pure gases, are also used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, submarines, space suits, spacecraft, medical life support and first aid equipment, high-altitude mountaineering and anaesthetic machines. Oxygen is the essential component for any breathing gas, at a partial pressure of between roughly 0.16 and 1.60 bar at the ambient pressure. The oxygen is usually the only metabolically active component unless the gas is an anaesthetic mixture.
