A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the substance has the same properties, for instance mixture's physical properties, such as its melting point, may differ from those of its individual components.
The physical properties are of course different. The chemical properties are considered identical but this is not a general rule; for example hydrogen isotopes (1H and 2H) have some different chemical and biochemical properties.
Allotropes have the same atomic number, number of protons, number of electrons, etc. but the chemical and physical properties may differ strongly.
Their atoms have the same number of protons and electrons and therefore have the same chemical properties. However, the atoms do differ in the number of neutrons and so their physical properties are slightly different.
chemical properties cannot be determined just by viewing or touching the substance and physical properties can be observed or measured without changing the composition of matter.
There are a lot of reasons why paper's physical properties differ from water's physical properties.Paper is a solid, water is a liquid.Water is transparent, paper is not.Water flows smoothly, paper does not.etc.
Isotopes are exactly same with respect to all the chemical properties but they differ with respect to physical properties.
A physical change would be a change in a physical property. A "physical property", by itself, may or may not change.
Isomers have different physical and chemical properties.
Conductivity
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
Physical properties: paint is a thick colored liquid with a distinct smell. Chemical properties differ depending on the paint...poster paint, oil-based house paint and car paint have vastly different chemical properties, but they're all paint.
A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the substance has the same properties, for instance mixture's physical properties, such as its melting point, may differ from those of its individual components.
It's a physical property because only the appearance changes, ie, the chemical properties are still the same. Ice and liquid water are chemically the same, but differ physically.
The physical properties are of course different. The chemical properties are considered identical but this is not a general rule; for example hydrogen isotopes (1H and 2H) have some different chemical and biochemical properties.
The properties of the compound will differ from the properties of the elements of which it is made.
