CHEMISTRY – WHAT IS Isotopes

In Dalton’s Atomic Theory, all the atoms of an element were considered alike in all properties including their masses. Later on, it was discovered that atoms of the same element can possess different masses but same atomic numbers. Such atoms of an element are called isotopes. So what really are isotopes? Isotopes can be defined as, “Different kind of atoms of the same element having a same atomic number, but different atomic masses”. Having same → Read more

CHEMISTRY – KINETIC MOLECULAR THEORY OF GASES

The behaviour of gases had already been described by the gas laws. These laws were based on experimental observations and were quite independent of the nature of a gas. In order to illustrate the behaviour of gases quantitatively, Bernoulli (1738) put forward Kinetic Molecular Theory of Gases. This theory led by Clausius (1857) to derive the kinetic equation and he therefore; deduced all the gas laws from it. The theory was later on elaborated and → Read more

MATH – TRICKS FOR SIMPLIFYING SQUARE ROOTS

Extracting the square root is something every mathematics student will have to do time and again during his mathematics career.The majority of the modern students feel that since calculators can find the square roots, they do not need to know the steps for deriving these values using pen and paper. Following this trend, it is not a big deal that your mathematics book is devoid of the lesson to find square root without a calculator. → Read more
