In a homogeneous mixture, the components completely mix with each other. These properties can be classified into two categories – physical properties, such as colour, odour, melting point, boiling point, density, etc., and chemical properties, like composition, combustibility, reactivity with acids and bases, etc.ġ) What is mixture ? What are the types of mixture ?Īns – A mixture is a combination of particles of two or more pure substances which may be present in it in any ratio. Examples of some compounds are water, ammonia, carbon dioxide, sugar, etc.ģ) What are two category can be used to classify properties of substance ?Īns – Every substance has unique or characteristic properties. They canbe separated by chemical methods. Moreover, the constituents of a compound cannot be separated into simpler substances by physical methods. They completely occupy the space in the container in which they are placed.Īns – When two or more atoms of different elements combine together in a definite ratio, the molecule of a compound is obtained. (iii) Gases have neither definite volume nor definite shape. They take the shape of the container in which they are placed. (ii) Liquids have definite volume but do not have definite shape. (i) Solids have definite volume and definite shape. these states of matter exhibit the following characteristics: consist of only one type of atom.Ĥ) Water molecule comprises …hydrogen atoms and … oxygen atom.ĥ) Which of the following is not an example of Physical Properties of substance.?ġ) What Are The Characteristics Of The Different States Of Matter?Īns – The three primary states of matter include the solid-state, the liquid state, and the gaseous state. (Refer Textbook Page No – 1-7)ġ) Which of the following state of matter have definite volume but do not have definite shape ?Ģ) Particles are held very close to each other in … in an orderly fashion and there is not much freedom of movement.ģ) Particles of …. Measurement of physical properties does not require occurance of a chemical change. The measurement or observation of chemical properties requires a chemical change to occur. Physical properties can be measured or observed without changing the identity or the composition of the substance. These properties can be classified into two categories - physical properties, such as colour, odour, melting point, boiling point, density, etc., and chemical properties, like composition, combustibility, ractivity with acids and bases, etc. When two or more atoms of different elements combine together in a definite ratio, the molecule of a compound is obtained.Įvery substance has unique or characteristic properties. These particles may exist as atoms or molecules. Particles of an element consist of only one type of atoms. Pure substances can further be classified into elements and compounds. A mixture may be homogeneous or heterogeneous. Matter can be classified as mixture or pure substance. They completely occupy thespace in the container in which they are placed.

(iii) Gases have neither definite volume nordefinite shape. They take the shapeof the container in which they are placed. (ii) Liquids have definite volume but do nothave definite shape. (i) Solids have definite volume and definiteshape. different states of matter exhibitthe following characteristics: However, in gases, the particlesare far apart as compared to those present insolid or liquid states and their movement iseasy and fast. In liquids, theparticles are close to each other but they canmove around. solid, liquid and gas.Particles are held very close to each otherin solids in an orderly fashion and there is notmuch freedom of movement. matter can exist in threephysical states viz. Chemistry plays a central role in science andis often intertwined with other branches ofscience.to understand thebasic concepts of chemistry, which begin withthe concept of matter. It is the science not so much of the one hundred elements but of the infinite variety of molecules thatmay be built from them.
