what are physical and chemical properties of iron?
220550
Physical and Chemical Properties Iron, like other metals, conducts heat and electricity, has a luster, and forms positive ions in its chemical reactions. Pure iron is fairly soft and can easily be shaped and formed when hot. Its color is silvery white. Iron is easily magnetized.

Characteristics such as mass, volume, color and temperatures are physical properties. Chemical Properties of matter are the ability of substances to react with or change into other types of matter. ... Some characteristics can describe a substance but do not, by themselves, identify the substance.

Minerals have distinguishing physical properties that in most cases can be used to determine the identity of the mineral. ... Among the properties we will discuss are: crystal habit, cleavage, hardness, density, luster, streak, color, tenacity, magnetism, and taste.

physical and chemical properties. Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density. There are many more examples.

Physical Properties. A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. ... Physical properties of matter include color, hardness, malleability, solubility, electrical conductivity, density, melting points, and boiling points.

Properties of Ferrous Metals Ferrous metals may include a lot of different alloying elements. Some examples are chromium, nickel, molybdenum, vanadium, manganese. Those give ferrous steels material properties that make them widely used in engineering.

Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.

Some of the important characteristics of materials are : strength, durability, flexibility, weight, resistance to heat and corrosion, ability to cast, welded or hardened, machinability, electrical conductivity, etc.

All matter has physical and chemical properties. ... Chemical properties describe the characteristic ability of a substance to react to form new substances; they include its flammability and susceptibility to corrosion. All samples of a pure substance have the same chemical and physical properties.

Chemical properties are very useful in identifying substances. However, unlike physical properties, chemical properties can only be observed as the substance is in the process of being changed into a different substance. Iron metal rusts. Mercury is a very dense liquid.
