Randomness is natural and more probable: high entropy. On the other side, if this sugar cube is dissolved in water, molecules are separated and spread randomly in water and the entropy is high. The probability of having that organization naturally is almost zero. In a chemical reaction, the increase of the entropy(s) plays in favor of the reaction.Īnother example, take a sugar cube, it is well organized, each molecule has its place and surrounded by a certain number of neighboring molecules. That is the same in nature, things in nature tend to be disorganized and that is the most probable natural situation.

Are you going to find them organized in a certain order such as by size, alphabetical names, by gender, etc.? The most naturally probable situation you are going to find them on the playground is in disorder, randomly organized i.e. Imagine students on the playground for their break. Widely defined as a measure of disorder, randomness or probability (possibilities) of organization of matter.

External energy supplied or applied to the matter.

Internal energy: energy stocked in matter, attraction and repulsion forces between particle of the matter.

The factors or driving forces behind the changes of matter are:

Rusting of a metal such as iron in air forms rust.

Heating limestone at high temperature forms quicklime and carbon dioxide.

Burning wood produces carbon dioxide, water, carbon and energy.

Changes of states of matter: vaporization and condensation of water.Ĭhemical phenomena, chemical processes or chemical changes are changes that affect the nature of matter and change it into another matter.

Physical phenomena, physical processes or physical changes are changes that affect the physical properties of the matter, but not the nature of matter.

What are the factors or driving forces behind the changes of matter?ĭifferences between physical phenomena, also called physical processes, and chemical phenomena or chemical processes.

The locked library: Tendinosis causes cells to reorder.

What’s the difference between physical processes and chemical processes? Give examples to illustrate. Violent physical and chemical processes take place during irradiation, many of which have been poorly.In our study here, we’ll be interested in two main categories of processes: Those processes can be put into different categories: physical, chemical, biological, etc. We live in an environment where many and different processes or phenomena take place. The next section will focus on the changes that matter can undergo. In the previous section, our study was focused on matter, its composition and how it is made and some of its properties.
