Matter

This topic details the different physical and chemical properties of matter. It describes various systems for the measurement of the physical quantity and international system of units. We will study the characteristic properties of matter.

This topic explains the kinetic theory of matter. We will study the main postulates of this theory regarding the motion of the particles. We also learn that the kinetic theory explains the difference between the three states of matter.

In this topic, we will learn about different states of matter with their examples. It also discusses about solids, liquids and gases in detail.

This topic highlights different states of matter and explains how they are differentiated on the basis of molecules present in it. It explains how matter changes its state when heated and how solid changes to a liquid and liquid changes to a gas.

This topic details different laws of combination. It explains the law of conservation of mass, definite proportion and multiple proportions. Avogadro’s laws and Gay Lussac’s law of gaseous volumes are also explained here.
