Different types of substances are present around us. These may vary in composition, or in their physical state. One of these types of substances is
Many of the material around us are mixtures. These mixtures have two or more than two substances (or constituents) mixed in them. It may not
A solution may have a small amount of solute dissolved in it while another solution may have a large amount of solute dissolved in it.
We may observe many types of substances that are present around us and find that they differ in shapes, size, compositions etc. Substances also differ
What is a colloidal solution? A colloid is a kind of solution in which the size of solute particles is intermediate between those in true
A pure substance is one which is made up of only one kind of particles. These particles may be atoms or molecules. So, we can
There are some changes during which no new substances are formed. On the other hand, there are some other changes during which new substances are
Newton’s second law of motion focuses on rate of change of momentum. We know that momentum is mass multiplied by velocity. Law of conservation of
The motion of bodies around us was associated with forces acting on them by the three laws of motion given by Isaac Newton. These three
Newton gave three remarkable laws for understanding the motion of bodies and relate it with force. newton’s third law of motion is also called action
Inertia and Mass – The first law of motion given by Isaac Newton was also known as law of inertia because Newton used the concept
