A type of gas is a classification in which a gas falls under that describes its properties. Gases can be classified as oxidizers, inert gases and flammable gases.
Oxidizing gases are not flammable gases but contribute to a combustion reaction. They should not be used in combination with fats or oils. Inert gases do not react with other substances and do not participate in combustion reactions. When an inert gas is emptied into a room or space, it reduces the amount of oxygen present and limits the process of combustion. This principle is applied in extinguishing systems. Flammable gases combine with air or oxygen and burn or explode.
A gas is one of the three states of matter, including solids and liquids. Gas particles contain large amounts of energy but are less organized than particles of other matter states. They are spread out over a greater distance and move more randomly. Gas has the ability to expand or compress to fill a container. This is done with a manipulation of the pressure of the gas as well as changing the temperature. Gases move from areas of high pressure to areas of lower pressure. If a gas is a liquid at room temperature, it is referred to as a vapor.Learn More
Copper is a metallic solid in its conventional state. As a solid, the molecules of copper occupy a stable configuration known as a crystal lattice. If the temperature is above 1,984 degrees Fahrenheit, solid copper melts and becomes a liquid. Copper becomes a gas at temperatures above 4,643 degrees Fahrenheit.Full Answer >
Heat is involved in chemical change in two ways; chemical changes either result in heat being added to or removed from an object, and chemical changes require a certain amount of heat before they can take place. Both of these two mechanisms of chemical change involve the heat characteristics of the involved substance or substances and the environment in which the chemical change is taking place.Full Answer >
Fire is not a form of matter; it is a chemical reaction. Fire is not made of any actual materials, but instead it is the result of chemical reactions from heating certain materials while they are in contact with oxygen.Full Answer >
Evaporation is a cooling process. It occurs because some particles in a liquid acquire more than average kinetic energy. Thus, when these particles escape from the liquid's surface as vapor or gas, they leave a cooling effect due to energy loss.Full Answer >
