WHY THERE ARE BLUE, GREEN, RED, AND BLACK ON PACKETS..... It shows that the thing is made of what, are these made by the chemicals, medicine, or by naturally. Blueline:- Blue line means that the products are made up of medicine and naturally and these lines are made at the corner or middle last of the products. Greenline:- Greenline means that the products are made up naturally and these lines are also there where the blue lines are.  Redlines:- Redline means that the products are made up naturally and by chemicals and these lines are also at that place. Blackline:- Blackline means that the products are made up of pure chemicals and some products which are having blackline are also harmful to us, for example, the creams, most of the beauty cream are made up of MICA, and mica is very harmful to our skin .

                      ABOUT MIXTURES About substance A pure substance consists of single type of particles. In other words, a substance is a pure single form of matter. And it is a homogenous mixture. Differences between HOMOGENOUS and HETEROGENOUS mixtures. Homogenous mixtures :- A mixture which has a uniform composition throughout such mixtures are called homogenous mixture for example are like salt is dissolved in the water or sugar dissolved in water. Heterogeneous mixtures :- A mixture which has a non-uniform composition throughout such mixture are called heterogeneous mixture for example are like mixture of sodium chloride and iron filings, mixture of salt and Sulphur, and oil and water. About the Suspension A suspension is a heterogeneous mixture the particles of suspension are to small that we cannot see them with our naked eyes, and scatter the beam of light passing through it and make the path visible. About the colloida...

  BIOLOGY Biology is the study of natural science concerned with the study of life and living organisms I.E., plants and animals.  The word biology is the combination of two words botany and zoology. Botany means the plants, which keeps the knowledge of plants. Zoology means the animal, who keeps the knowledge of animals are called zoologisTS. bIOLOGY IS THE COMBINATION OF ZOOLOGY AND BOTANY.  THE BIOLOGY IS COINED BY LAMARCK AND TRIVIRANUS.  THE SCIENTIST WHO GAVE HIS THOUGHT FOR THE FIRST TIME ABOUT THE LIFE OF PLANTS AND ANIMALS WAS ARISTOTLE.  THAT’S WHY HE IS KNOWN AS THE FATHER OF BIOLOGY. HE IS ALSO KNOWN AS THE FATHER OF ZOOLOGy.  THE FATHER OF BOTANY IS THEOPHRASTUS.

                    Separation of Mixtures   Different methods of separation are used to get individual components of a mixture. Separation makes it possible to study and use the individual components of a mixture.  A heterogeneous mixture is used to separate the components. For example, if we take ink, water, and burner take a test tube to keep it on the burner and put some water in the test tube and now take a plate to cover the top of the test tube and on that put the ink on the plate and the ink is the mixture of water and DIY well after some time you will see the ink that the DIY is and the water gets disappear it is because the water which was kept in the test tube it was getting heat due to the heated water was producing water vapors and the water vapor was heat and it was giving heat to the ink and the ink particles mixed with the vapors and fly in the sky with air and you will see that the ink is like a powder well tha...

     What are Pure Substances? -   A pure substance consists of a single type of particles. In other words, a substance is a pure single form of matter.          About The Mixture -  Mixture that contains more than one or single type of particles or pure substance is called a mixture.     Types of Mixture   -  There are three types of mixture and are colloidal , solution , and  Suspension.  -   Colloidal- A particle must be disappeared in a liquid and others extend the definition to include substances like aerosols and gels are called colloidal. -    Solution- Solution is a special type of Homogenous mixture which contains two or more substance is called a solution. -    Suspension- Suspension is a Homogenous mixture of finely distributed solid in a liquid.

                              About Diffusion The intermixing of two particles is called Diffusion. For example, if we take water and sugar and mix the sugar with water then the sugar crystals will start breaking down and fill the spaces between the particles of water and the sugar crystal will break down till the spaces are not fill and after that, it will fully dissolve with water.                     About Kinetic Energy When the heat is supplied to the particles of matter and it reacts with the power of heat is called kinetic energy. For example.....   If we take 100ml of water and 100grms of sugar and take two glass put the sugar and water the same amount in both glass and one will be kept in the room temperature and another we will give heat and you will see that the glass which is kept in the room temperature then the sugar will take to time to di...

Matter which occupies the space, Everything in this Universe even a small particle is called matter. Which have their own shape, size, texture, mass, and volume is called matter. -State of Matter There are three types of state of Matter and are Solid State, Liquide State, and Gaseous State  -Characteristics of Matter                                             There are three characteristics of Matter and are Particles of Matter have...
