Examples of physical changes--All objects/materials that exist in the world is the embodiment of a substance where it is composed by up to hundreds of billions of atoms. Atom atom is what will determine the characteristics of the material.Before continuing your reading activities, help us to click the image on the side.Abnormal conditions, the material will undergo changes so that the form andwill not be completely identical with the original form. However on some andwill return to its original shape.
In this article we will discuss about the physical change examples of a variety ofsubstances, but did not close the possibility there were some changes to the physics of a material that is not mentioned, so we hope that friends commentedand ask if there is there is confusion.
The change of Physics involves the State of matter and energy. There is no newsubstance created during physical changes, although this took different forms.Size, shape, and color of the material can be changed. Also, the change of physics occur when substances are mixed, but it's not a chemical reaction. One way to identify changes in physics is that the changes are reversible, occursmainly changes phase. For example change the physics, if we freeze ice cubes, we can mencairkannya into the water again. the process of changing the form of physics material of this nature is affected by mechanical forces on the and.

What is a Physical Change?
Each type of change that occurs without changing its chemical composition, is the change in physics. The change of physics is marked by the change of the physical attributes associated with any object, such as a State of matter (solid, liquid or gas), density, temperature, volume (or shape), which took place without the modifications in the chemical structure of fundamental. There is nocreation of new chemical products or change the overall mass. Also, these types of changes are usually temporary and in some cases, completely reversible.
