1) Evaporation of water. 2) Formation of dew. 3) Crystallisation of sugar from its solution. 4) Ringing of an electric bell..

The technological development of any society is very closely related with the application of physics and other branches of science. The study of heat and thermodynamics is one of the main initiators of the industrial revolution. Today we see the applications of physics in eve..

Let f, g be two functions defined by $f(x)=\sqrt{x+1}$ and $g(x)=\sqrt{9-x^{2}}$, describe the following functions: (i) f+g (ii) g-f (iii) gf (iv) $\frac{f}{g}$ (v) $\frac{g}{f}$ (vi) $2f-\sqrt{5}g$ (vii) $f^{2}+7f$ (viii) $\frac{3}{8}$. Solution. Given $f(x)=\sqrt{x+..

1. Physical state: Dimethyl ether and ethyl methyl ether are gases at room temperatures. Other lower members are colourless liquids, which are highly volatile. 2. Boiling points: Ethers have much lower boiling points compared to isomeric alcohols as they are not associated with..

(1) Taste : Acids have a sour taste. Mineral acids like H 2 S0 4 and HN0 3 are highly corrosive in nature. Therefore, they should not be tasted. (2) Physical state : Some acids are solids and some are liquids at room temperature. For example..

In physical change only physical properties of substances such as state, volume, density, elasticity, malleability, ductility, porosity, etc. may change. Common examples observed in daily life, are dissolution of sugar and common salt in water, transformation of ..

Based on the nature of the type of forces responsible for adsorption on the surfaces of the adsorbents, adsorption is classified as i. Physical adsorption or physisorption and ii. Chemical adsorption or chemisorption i. Physical adsorption : If the forces that are res..

For quite a long time, length, mass and time alone were considered as fundamental physical quantities. The fundamental physical quantities are those, whose measurements do not depend upon any other physical quantities. The units of such quantities are known as "funda..

. (b) the numerical value (magnitude) of physical quantity. We may write Physical Quantity = Magnitude * Unit If unit of measurement is small, then numerical value of the physical quantity is very large and vice versa. Types of Units There are two types,of units : (a) ..

-rays. X-rays and other radiations damage DNA and initiates malignant tumour. The luminescent paint used in painting the dials contain radium, which is carcinogenic. A more horrifying example of radiation - induced cancer occured in Japan after the atomic bombs were exploded over Hiroshim..
