what is the difference between gas and fume?

Fume - Solid particles generated by condensation from the gaseous state, generally after volatilization from melted substance (e.g. welding), and often accompanied by a chemical reaction such as oxidation. Gases and vapours are not fumes. Gas - A substance that is in the gaseous state at room temperature and pressure.

what is the difference between density and vapour density? Density is the ratio of mass of a substance to its volume. Vapour density is the ratio of weight of a certain volume of gas or vapour compared to the weight of an equal volume of hydrogen .

What is the difference between mass flow and volumetric flow? Mass flow measures the number of molecules in a flowing gas. ... Volumetric flow rate is a measure of the 3-dimensional space that the gas occupies as it flows through the instrument under the measured pressure and temperature conditions.

Originally Answered: What is the difference between air and gas? Air is a collection of different gases. Mainly nitrogen, and then oxygen. Gas is loosely bound atoms of an element or collection of such in compounds above the temperature required to make them liquid, and colder to make them solid.

Properties of Matter: Gases. 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.

The difference between biogas and natural gas is that biogas is a renewable source of energy whereas natural gas is a non-renewable source of energy. In addition to that, biogas is a naturally occurring gas that forms from the breakdown of organic matter in the presence of anaerobic bacteria.

Water vapor is little water droplets that exist in the air, while steam is water heated to the point that it turns into gas. In simplified science, both are referred to as the gaseous state of water. However, the main difference between them lies in temperature. ... This is evaporation a form of water vapor.

In particular, the mass density of nitrogen gas is similar to methane, while carbon dioxide is much heavier than methane in reservoir conditions. These differences cause loss of inert gas or productivity to vary.

If an object containing a gas floats on air, it is less dense than air vs. if it sinks, it is more dense than air. Gas Density examples based upon differences in molecular weight. Density of a gas with a constant number of molecules in a constant volume, varies according to the molecular weight.

Tell students that gases are made of molecules but that the molecules are much further apart than the molecules in liquids or solids. Since the molecules of a gas have mass and take up space, gas is matter.

1 Answer. Steam is water in a gas phase, while mist, or fog, are small droplets of water in the condensed phase, but small enough to be kept in the air by thermal Brownian motion. ... It is an invisible gas, and contains a large latent energy which is released when the steam condenses into droplets.

Air is a gas while water is a liquid. Air is compressible while water is for all purposes non compressible. Water is H2O with some dissolved solids and gases while air is a mixture of all gases with some water in the form of vapor.

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. There is a great deal of empty space between particles, which have a lot of kinetic energy. ... The particles exert more force on the interior volume of the container.

The atoms and molecules in gases are much more spread out than in solids or liquids. ... A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.

While natural gas is composed of mainly methane (which is made from a majority of hydrogen), gasoline is composed of carbon compounds. ... Because natural gas is made of mainly hydrogen, it produces fewer harmful emissions (such as carbon monoxide and carbon dioxide) than gasoline.

Natural gas is mostly methane that's been pressurized into a liquid. ... Natural gas is simply cleaned before use to make it more efficient. On the other hand, propane is a refined fuel. Propane is a hydrocarbon, like butane and ethane, that is part of other materials.
