𝐓𝐞𝐫𝐦𝐬:-
i. Pure substance :- Pure substances are the substances which are made up of only one kind of particles. ex: Oxygen, water.
Characteristics of pure substances:-
i. Pure substances are homogeneous in nature.
ii. Pure substances have fixed set of properties.
iii. Pure substances cannot be separated into other kinds of matter by physical process.
Elements :- Elements are the pure substances which cannot be broken down into simpler substances by any physical or chemical process as they are made up of only one kind of particle. e.x - oxygen, nitrogen etc.
Metals, Non metals, mtellaloids: Boron, arsenic, antimony, silicon, germanium...
Have Properties intermediate between metal and non metals.
Compound - Compound are the pure substances which are made up of 2 Or more elements chemically combined together in a fixed proportion by mass. e.x - CO2, H2O etc.
Characteristics of compound:-
i. Elements in compound are chemically combined together in a fixed proportion.
ii. The properties of compound are very different from it's constituent elements.
iii. Compound has fixed melting and boiling point.
iv. Constituent elements which made up the compound can be separated by chemical processes. ex water by electrolysis.
v. Compounds are homogeneous in nature.
Mixture:- Mixture is an impure substances which consist of 2 or more elements or compounds not chemically combined together.e.x Tea, Air, milk etc
There are two types of mixture :-
i. Homogeneous mixture
ii. Heterogeneous mixture

1•) Homogeneous mixtures: Those mixtures in which substances are completely mixed together and are indistinguishable form one another are called homogeneous mixtures.
It has uniform composition.
It has no boundary of separation between the various constituent.

44:17 DOUBT QUESTION

In our previous discussion about matter, we learned that matter is composed of particles. When a substance, like sugar, is dissolved in another substance, such as water, the sugar particles separate and spread among the water molecules. In this chapter, we are studying the chemical properties of matter. You have explained that mixtures are substances made up of two or more elements and compounds that are not physically combined. You have also explained that homogeneous mixtures are those mixtures in which substances are mixed and are indistinguishable from one another.

An example of a homogeneous mixture is tea, which is made up of various constituents (like tea leaves, sugar, milk, ginger, and some other ingredients). So, can we say that the tea constituents have separated into intermolecular spaces between the water molecules? When preparing tea, heat is absorbed or released, but a mixture doesn't require any heat for its formation. Since a homogeneous mixture is also a type of mixture, why are we considering a homogeneous mixture as a mixture?

44:17 TEA [Homogeneous Mixture]

The resulting mixture looks uniform because the dispersed particles or molecules are too small to be seen individually. There are no visible layers or separate phases.When you taste the tea, the uniform distribution of the components means that each sip contains the same proportions of water, milk, tea compounds, and sugar. This is why it tastes the same throughout.
