Chemistry In Our Daily Life
Chemistry is a big part of your everyday life. You find chemistry in daily life in the foods you eat, the air you breathe, your soap, your emotions and literally every object you can see or touch. We live in a world of matter. From the food that sustains our lives to various objects that have built up our physical culture, everything is made up of matter. The human body itself is a mixture of matter of differing types. The humans who used materials obtained from nature for centuries, later made new materials out of these to suit their needs. Now the humans have thousand of materials for their use - both natural and human made. The ability that humans acquired to make new materials from natural materials is the basis of human progress. When the structure of the material world and the nature of physical and chemical changes in them were studied, humans were able to make new materials and to control their different properties. The development of chemistry made this progress possible. The contribution of chemistry to fields like, agriculture, industries, health care, food industry, habitat, transport and research has been invaluable.
1. You feel hungry because of the satiety center in your brain falls short of particular hormones to function and then sends the signal of hunger.
2. If you have wondered, why is the sky blue, it is due to a phenomenon called the "Rayleigh scattering", which depends on scattering of light through particles which are much smaller than the wavelength. Hence when light passes through gases, there is scattering and the sky appears blue.
3. Coffee keeps you awake because of the presence of a chemical called adenosine, in your brain. It binds to certain receptors and slows the nerve cell activity when sleep is signaled.
4. Anaerobic fermentation is also a great concept which is present in the chemistry of everyday life. It is present in yogurt, breads, cakes and...
