Is brittleness chemical property?
Brittleness is a characteristic that describes chalk. Any such characteristic of a material that you can observe without changing the substances that make up the material is a physical property. Examples of physical properties include: color, shape, size, density, melting point, and boiling point.
What is brittle in chemistry?
Brittleness describes the property of a material that fractures when subjected to stress but has a little tendency to deform before rupture. Most of inorganic non-metallic materials are brittle materials.
Is brittle a physical or chemical Propertie?
Brittle- physical . Likely to break, fragile . Porous- physical. Having tiny little holes (pores) that allow liquid or gas through. -Chemical properties. Physical property. It is a characteristic of a pure substance that can be observed without changing it into another substance.
Is lightning chemical or physical?
Lightning is both a physical and a chemical change.As no new substance that is formed during this process, so it can be termed as a physical change. But at the same time chemical changes takes place in the cloud.
What is brittleness as property of metals?
Definition – What does Brittleness mean? Brittleness is a property of metals which states that they do not deform under load but suddenly break . It is basically the tendency of metals or a material to fracture or break even upon the application of small impact, force or shock.
Is solubility physical or chemical properties?
Solubility is a physical property. The reason is because it can be determined by simple observation and does not change the chemical composition of the material. For example, when salt dissolves in water, it is still salt.
