Extensive properties depend on the amount of matter present, for example, the mass of gold. For example, pure copper is always a reddish-brown solid (a physical property) and always dissolves in dilute nitric acid to produce a blue solution and a brown gas (a chemical property). For example, many elements conduct heat and electricity well, whereas others are poor conductors. Many elements are fairly soft (silver and gold, for example) while others (such as titanium, tungsten, and chromium) are much harder. The degree of difficulty required to cause the combustion of a chemical is quantified through fire testing. Yes, flammability is a chemical property. Both the drop and the pot of oil are at the same temperature (an intensive property), but the pot clearly contains much more heat (extensive property). WebChemical properties, such flammability and acidity, and chemical changes, such as rusting, involve production of matter that differs from that present beforehand. Nineteen grams of fluorine will react with 1.0 gram of hydrogen. A chemical change is a process in which one or more substances are converted into one or more new substances with different properties. All substances have distinct physical and chemical properties, and may undergo physical or chemical changes. 14.0 deg C (57.2 deg F) closed cup. (credit a: modification of work by 95jb14/Wikimedia Commons; credit b: modification of work by mjneuby/Flickr), (a) One of the chemical properties of iron is that it rusts; (b) one of the chemical properties of chromium is that it does not. For example, structural steel and concrete have high fire resistance and are often used in building construction. The periodic table shows how elements may be grouped according to certain similar properties. It is important to consider both flammability and toxicity when handling, storing, and transporting hazardous materials and to follow guidelines and regulations for their safe handling and transportation. In addition to flash point and flammability classifications, other factors that can affect the flammability of a chemical include its vapor pressure, ignition temperature, and ability to react with other chemicals.
