surface area of the tea cup. Temperature: At high temperature‚ rate of evaporation is high because at high temperature kinetic energy of molecules increases so high that they overcome the intermolecular forces ‚and‚ evaporate rapidly.For example‚ water level in a container with hot water decreases earlier than that of a container with cold water.This is because hot water evaporates earlier than hot water. Itermolecular Forces: If

Uses of water: 1. For drinking and for life processes. On an average‚ a man consumes about 60‚000 to 80‚000 litres of water in his lifetime. The body of an adult contains nearly 40 to 50 litres of water at any given time and water constitutes about 66% of the average body make up. Aqueous solutions fill the cells in the body. Nutrients‚ oxygen‚ and metabolic waste products are transported by blood‚ which is mostly water. Digested food is absorbed in the form of an aqueous solution. In plants too

the 200mL beaker started with an average temperature of 43.5oC it then gradually fell to 41oC after 45 seconds‚ then rapidly decreased in temperature by 2oC every 15 seconds. At the 90 second period it decreased by 4oC from 35.5oC to 31.5oC it then steadied out falling by 1oC per 15 seconds until the 120 second stop mark. For the 500mL beaker the temperature difference between the 15 second intervals were very different being more gradual with the temperature on average falling from 1 – 1.25oC per

“WATER IS A GOOD SOLVENT” Water is very unique in all facets of its nature. The chemical formula for water is H2O as a water molecule consists of two atoms of the chemical element hydrogen (H) and one atom of the element oxygen (O). Water is the most abundant chemical compound on earth as its mass all exists together‚ naturally‚ in its gaseous‚ liquid and solid state. It is the most precious natural resource to man and is essential to life for all discovered living organisms. One of the unusual

biological importance of water Water‚ the most abundant compound on the planet‚ is a material which is essential for all living organisms. Its uses in all living things cover a huge variety of everyday functions which are immeasurably important to the continuity of the organism. The fact that water makes up between 60 and 95 percent of all living organisms speaks for itself on the incredible biological importance of this compound. One of the major functions of water in living organism is its
