The phenomenon of change of a liquid into its vapour at any temperature below its boiling point is called evaporation. Wet clothes dry up in air due to the evaporation of water. Rate of evaporation increases with increase in temperature. The particles in a liquid have different kinetic energies. Some particles have lower kinetic energies and other have higher kinetic energies. The particles having higher kinetic energies at the surface of the liquid overcome the forces of attraction of other particles, leave the surface and get converted into vapour. Evaporation is continuous process and particles keep on escaping the surface of the liquid. 1. At what temperature evaporation takes place?

(i) At boiling point (ii) Above boiling point (iii) At room temperature (iv) Below boiling point 2. How do wet clothes dry-up?
(i) Due to condensation (ii) Due to evaporation (iii) Due to surface tension (iv) Due to temperature 3. What is the effect of temperature on evaporation?
(i) Increases with temperature (ii) Decreases with temperature (iii) No effect of temperature (iv) None of these 4. What type of energy do the particles have in a liquid?
(i) Electrical energy (ii) Potential energy (iii) Kinetic energy (iv) Radiation energy Passage No. 4
The measures adopted in health arena have increased the life expectancy to over 64 years in 2000. Infant mortality rate (IMR) has come down from 147 in 1951 to 75 in 2000. Crude birth rates have dropped to 26.1 and death rate to 8.7 within the same duration of time. Increase in life expectancy and improvement in childcare are useful in assessing the future progress of the country. 1. How much did the life expectancy increase in the year 2000? (i) 47 (ii) 75 (iii) 26 (iv) 64 2. What percentage of the infant mortality rate fell during 1951 to 2000? (i) 48.9 % (ii) 50 % (iii) 51 % (iv) 51.9 % 3. How much has been the growth rate between 1951 to 2000?

(i) 8.7 (ii) 17.4 (iii) 26.1 (iv) 64 4. How much did the death rate reach in 2000?
(i) 7.5 (ii) 8.7 (iii) 6.4 (iv)...
