Three State Of
Good morning sir, good morning friends. How are you today? Okay every body, in this opportunity, I want to tell you all about a matter around us.
Everything in this world is certain consist of three state matters. They are solid matter, liquid and gas matter. Each have a differently characteristics. Okay, now I will explain them one by one.
Let’s begin from figure number one. It is a solid matter. Solid is a matter which has a fixed shape and volume. Characteristics of this matter are:
§ Have strongly union each molecules
§ Have a fixed shape and volume
§ Will expanse on heating
§ Will shrink on freezing
There are so many things around us which shape are solid matter. For example are a table, a chair, a board, a rock, etc. that things are have a solid matter characteristic. So that things are include a solid matter.
Then, figure number two. It is a liquid matter. A liquid is very different with a solid matter. A liquid is has no fixed shape. It shape changed easily due to the container. Characteristic of this matter are:
§ Have no stable shape. Changed due to the container
§ Only have a stable volume
§ Flow from high area into low area
§ Will evaporate on heating and frozen on freezing
.
A liquid matter is always found around of us. Every time every where. Water, a liquid ink, an ice tea, lemon tea, and more other. And they are also having liquid characteristics. For example the easiest. Water, the shape will like it container. Like a bucket on a bucket. Like a glass on a glass. It is due to the container. Then water will evaporate if boiled. And become an ice in freezing. On a river, water always flow from high area into low area. So it is have all of liquid characteristics.
The last kind of matter is gas matter. It is so different wit other matter. It is has no shape. Characteristics of this matter are:
§ Has no shape, has no color but smelled.
§ Pressing to all of direction.
§ Have a fixed volume
In the air, gas is consisting of many kinds. But main components of the air are Nitrogen and Oxygen. A presentation is 79 % Nitrogen and 21 % Oxygen. But beside both gases, there are so many kinds of gas include it. But a presentation is very little. It is only reach PPM number. PPM is part per mill. So it is very little on the air. For example are carbon dioxide, carbon monoxide, helium, methane, and more other.
Okay every body, that way a full of my presentation. Sorry for all mistakes, and thanks you for the attention.
