Since gas molecules can move freely within a container, their mass is normally characterized by density. Density is the amount of mass per unit volume of a substance, or the inverse of specific volume. For gases, the density can vary over a wide range because the particles are free to move closer together when constrained by pressure or volume.


Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOCs are ...


The industry producing these gases is also known as industrial gas, which is seen as also encompassing the supply of equipment and technology to produce and use the gases. Their production is a part of the wider chemical Industry (where industrial gases are often seen as " specialty chemicals ").


American Chemical Society: Chemistry for Life. What are “greenhouse gases?” The transparent windows of a greenhouse (or a car parked in the sunlight) transmit the warming visible rays of the sun, prevent the resulting warm air from leaving, and hence maintain a warmer environment inside than outside the structure.


Some greenhouse gases are emitted naturally through wildfires, volcanic activity, and biological activity. However, since the industrial revolution at the turn of the 19 th century, humans have been releasing increasing amounts of greenhouse gases. This increase accelerated with the development of the petro-chemical industry after World War II.


Attractive Market Opportunities in Specialty Gases Market Estimated to Grow at a significant rate throughout the 2025 and Focusing Key players like The Linde Group, Air Products And Chemicals, 3M Company, etc


Gas bubbles are a chemical change. A common example can be soda. The bubbles in the soda are carbon, thus soda is carbonated, when you leave soda open and out in the open the carbon reacts with ...

Elements or compounds that are Gases at Room Temperature . Before examining the chemical and physical properties of gases, it might be useful to ask: What kinds of elements or compounds are gases at room temperature? To help answer this question, a list of some common compounds that are gases at room temperature is given in the table below.


Industrial handling of chemicals and gases Dangerous chemicals and gases are handled and stored at nearly all chemicals and explosives plants, oil refineries, pulp and paper plants, paint factories, paintshops, power plants, water purification plants, ports and many other facilities.
