Water is a substance that is in great abundance on this planet, and it holds some significant importance to our lives. Without it, we could not live, and not simply because we would die of thirst. Some of the notes here are also relevant to AS Chemistry, but be careful, as different specifications might ask for information on different anomalous properties, so make sure you check your exam syllabus! The Properties of Water Water is a dipolar molecule:
Without it, life would not be possible as seen on other planets in our Solar system. Hence air is a natural virtue on earth which sustains life. The composition of air and its properties can be studied in physics and chemistry.
Air consists of many gases like nitrogen, oxygen, inert gases in varying proportions. But, due to industrialization, there is the rise in air pollutionrendering it unsafe for breathing. Essential supplier of energy: Body cells take up oxygen from the blood and generate energy from food in the form of ATP.
This biochemical generation of ATP is an essential requirement to sustain life on earth. Air is a conducting medium for sound: We can hear the sound of speech or cry or noise etc. This is because air is a good conductor of sound. Even the music instruments make use of resonance and bass with the alteration of air and sound combination.
Air supports water cycle: These clouds travel on to the land surface, get cooled by air and shower as rain.
This rainwater somehow again reaches the Sea and Oceans. So air helps in transfer or movement of clouds towards the earth surface and also cools them to shower the rain. Air helps in pollination of crops: This is called as pollination. This can happen within flowers of the same plant or between distant ones through air wind.
Thus air helps in cross-pollination in plants. Henceforth going into a grown farm causes nasal stuffiness as the pollen cause allergy to nasal tract when breathed in. This helps in agriculture as cross-pollination leads to higher yield. Air maintains temperature on the earth surface: So air which gets heated on earth surface rises and cold air from sea surface moves on to the earth surface thus minimizing the rise in temperature.
Monsoons are the ones by which we have rains in the rainy season. This is done due to currents of wind air across the earth surface. Lack of wind can delay monsoons and rains and thereby deplete water levels for drinking, irrigation and another usage in our daily lives.
Air helps in transport: Air transport by flights and helicopters has come into widespread use. Even for birds and insects air is the chief mode of transport. Air transport is quicker than land and water transport.
There is less friction, so the vehicles travel faster.
Further, the travel is in vector mode, i. So the journey has fewer obstructions making the transport very fast. Parachutes, hot air balloons are used to land from flights in case of need safely.
These flying chute reach the land safely due to buoyancy and pressure of air upwards. Air helps in drying humidity balance: Land when gets wet by rains is dried due to air.
The air on the immediate wet surface is very moist. So these moist layers of air are replaced by less moist or dry layers of air.
Even our clothes when washed gets dried by same manner. Air helps in normalizing Temperature: A piece of ice melts due to air and hot piece of metal cools due to air.
Here air acts as a heat conductor and tries to bring these materials to normal surrounding temperature. Hence the phenomenon of ice melting and metal cooling is seen.Water is important for life due to its many roles and functions in chemistry, biochemistry and biology that result in water being, not just important, but essential to support life.
These functions of water in biology are due to the diverse properties of water, that is - the way it behaves, both chemically and physically. This table lists some of the . Biological Molecules [back to top] Life on Earth evolved in the water, and all life still depends on water.
At least 80% of the mass of living organisms is water, and almost all the chemical reactions of life take place in aqueous caninariojana.com other chemicals that make up living things are mostly organic macromolecules belonging to the four groups proteins, nucleic acids, carbohydrates or lipids.
