Do all samples of a substance have different physical properties?
All samples of a substance have different physical properties. Hardness, color and boiling point are physical properties because they can all be observed and/or measured without manipulating the composition of the substance.)
Can the same substance have different properties?
Chemical Properties and Change Chemical changes occur when bonds are broken and/or formed between molecules or atoms. This means that one substance with a certain set of properties (such as melting point, color, taste, etc) is turned into a different substance with different properties.
Are physical properties always the same for the same substance?
All samples of a pure substance have the same chemical and physical properties. 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).
Is it possible that the two things that have identical physical properties will have different chemical property?
Other properties, such as density, can be used to identify substances. They do not vary from one sample of the same substance to another. However, it is possible for two different substances to have the same density.
How are physical properties different from chemical properties?
Anything that can be measured without changing the identity or chemical composition of substance is known as the physical property of a substance. A physical change involves formation of a new arrangement of matter but the structure of the atoms and molecules remain the same. Difference Between Chemical and Physical Properties
Which is an example of a physical property?
Sometimes it can be useful to distinguish between different types of properties. Physical properties refer to properties that can be observed or measured without changing the composition of the material. Examples include colour, hardness and smell and freezing, melting and boiling points.
Is the composition of a pure substance the same?
composition of all phases is the same. Phases of a Pure Substance A pure substance may exist in different phases. There are three principal phases solid, liquid, and gas. A phase: is defined as having a distinct molecular arrangement that is homogenous
How are the properties of a material discovered?
Chemical properties are discovered by observing chemical reactions. They include combustion point, reactivity with acids and toxicity. Processes such as mixing, heating and cooling can change materials and their properties. This can be useful as the new properties may be better suited for particular purposes.
