The Types of Mixtures: Homogeneous & Hetrogeneous

Mixtures are two types:

• Homogeneous mixture: is made up of two or more substances forming only one phase. Also it possesses the same properties through out its parts. the source: builing up enviroment and economyhttp://community.ecoseed.org/service/searchEverything.kickAction?as=29468&mediaType=blog&sortType=rating&includeBlog=on&d-7095067-p=1
  Water is considered as a homogeneous mixture because it only has one phase .

• Hetrogeneous mixture: is made up of two or more substances forming different phases. also it does not possess the same properties in all its parts.

If you look at this dish of soup we will observe that it consist of more than two phases. Forthat, we consider it as a hetrogeneous mixture.

Command: do these experiments by your self to be sure of the results and inorder to understand more.

Mixtures & Pure Substances

• A pure substance is made of only one kind of material.


• Since distilled water has always the same characteristics throughout and doesn't separate into other substances by simple means, then it is made of one kind of material and hence it is a pure substance.

• A mixture is made of two or more than one kind of material.

• The boiling point of pure substance is constant.



• The boiling point of a mixture is variable.

Question: Can any substance of the material be separated into two or more substances by simple means?

Basic States of Matter

Matter exists in three basic states solid, liquid, or gas.
A solid has a definite shape regardless of the container in which it is put.
A soild has a definite volume.
A liquid has no definite shape but takes the shape of the container in which it is put.
A liquid has a definite volume (at the same temp)
A gas has a definite shape nor a definite volume. It takes the shape and volume of its container.

Question: In what ways are the three states similar or different ?

Introdution

Matter exists in three basic states solid (table, jar, and chair) liquid (juice, water, and tea) and gas (air, balloon, and ball). They differ from each other in two things, which are the volume and shape. But, they have some similarities, which we will talk about them later in this chapter. Moreover, in this chapter we will talk about the mixtures and the pure substances, and the differences between them. And we will go in the details of the mixture solution, by talking about the two different types of mixture:" homogeneous and heterogeneous."

Question: Can you find another way of classification for the contents of the objects below?

welcome

Welcome my lovely students. We will be conserned to talk about Matter and its different types in this chapter, including also some related topics. So I wish that you will enjoy this topic and understand it well.

Thanks & Good Luck !
