1. Everything is made of chemicals. You are made of chemicals. So is your dog. So is your desk. So is the sun. Drugs are chemicals. Food is made from chemicals. 2. Many of the changes you observe in the world around you are caused by chemical reactions. Examples include changing colors of leaves, cooking food and getting clean. 3. Knowing some chemistry can help you make day to day decisions that affect your life. Can I mix these household chemicals? What are safe mosquito repellents? Will my bottled water expire? Well, this involvement usually begins first thing each morning.
Most people wake up to an alarm or radio. These common household items contain batteries, which make them very chemically dependent. These batteries contain positive and negative electrodes. The positive electrode consists of a carbon rod surrounded by a mixture of carbon and manganese dioxide. The negative electrode is made of zinc. Chemistry plays an important role in the discovery and understanding of materials contained in these and many other common household items. Things like household cleaners and water purification systems are vitally dependent on chemistry.
Without chemistry something as simple as scrubbing a toilet without fear of severe burns or small explosions might not be possible. Next, though it isn’t widely known, chemistry is also heavily involved with the manufacturing of things such as makeup and soap. Each time you bathe you are witnessing chemistry at work. Chemicals such as acetyl alcohol and propylene glycol are typical ingredients in the soap used to wash your hair and skin. Without chemistry, these materials (or combinations of these materials) might be hazardous or might not exist.
The chemical coloring agents used in makeup and nail polish would not be possible without an understanding of the chemicals involved. Almost anything you do during the course of a normal day involves chemistry in some way. The gas and tires in cars we drive, the makeup we put on our faces, the soaps and cleaners used every day, burning wood or other fossil fuels, chemistry is all around you each and every day. The associations are practically limitless. Chemistry in Everyday Life Chemistry in everyday life: Our entire universe is made up of matter which is constantly changing forms and evolving into other forms of energy.
Chemistry is defined as the study or science of this ever changing matter. The other sciences which we study commonly like biology, physics and mathematics are all dependent on chemistry and are known as specific studies under the elaborate subject of chemistry. Since there is chemistry seen in biological forms as well as physical states of nature, there are subjects called biochemistry and physical chemistry which help study these changes. There are many chemical changes which occur around us every day but we are never aware of them.
Chemistry in Everyday Life Examples: 1) Water, which occupies 70% of the earth’s surface is made by two chemical elements, hydrogen and oxygen. 2) Soap is an emulsifier which allows oil and water to mix and so the oily mixtures on body and clothes can be removed after application of soap and water. 3) Chemistry in everyday life for kids can also include why vegetables are colored. Colored vegetables consist of chemical compounds called carotenoids which have an area known as the chromophore. It absorbs certain wavelengths of light and thus there are colored vegetables. ) Food is cooked because of the steam that’s present either in the water added or that which is present inside the food items. 5) Onions make you cry due to the presence of sulfur in the cells which break after the onions are cut. This sulfur gets mixed with moisture and thus irritates your eyes. 6) You feel hungry because of the satiety center in your brain falls short of particular hormones to function and then send the signal of hunger. 7) You fall in love, get attracted and have a feeling of belonging because of certain monoamines present in your brain which get stimulated through nerve sensors. ) Elements in the Human Body your body is made up of chemical compounds, which are combinations of elements. While you probably know your body is mostly water, which is hydrogen and oxygen. Most of the human body is made up of water, H2O, with cells consisting of 65-90% water by weight. Therefore, it isn’t surprising that most of a human body’s mass is oxygen. Carbon, the basic unit for organic molecules, comes in second. 99% of the mass of the human body is made up of just six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. ) Chemistry of Love the emotions that you feel are a result of chemical messengers, primarily neurotransmitters. Love, jealousy, envy, infatuation and infidelity all share a basis in chemistry. The sweaty palms and pounding heart of infatuation are caused by higher than normal levels of norepinephrine. Meanwhile, the ‘high’ of being in love is due to a rush of phenyl ethylamine and dopamine. 1. You feel hungry because of the satiety center in your brain falls short of particular hormones to function and then send the signal of hunger. 2.
You fall in love, get attracted and have a feeling of belonging because of certain monoamines present in your brain which get stimulated through nerve sensors. 3. 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. 4. 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. 5. Anaerobic fermentation is also a great concept which is present in the chemistry of everyday life. It is present in yogurt, breads, and cakes and many other baking products. It is the multiplication of certain useful bacteria which increase the size of the food and make it more filling and soft. 6. Soap is formed by molecules with a “head” which likes water (hydrophilic) and a long chain which hates it (hydrophobic). 7. Lactose is the main complex sugar found in the milk.
It’s a pretty big compound formed by two smaller components: glucose and galactose. Such a big compound cannot get through the intestinal wall and into the bloodstream, so we need “something” to break it into smaller pieces. This “something” is an enzyme named lactase. The more milk and milk products we consume, the more lactase we need. 8. The iodised salt is a necessary intake. It prevents a disease called goiter. 9. In the garden we use sprays to kill insects from attacking our plants. 10. Vermiwash is a liquid fertilizer. It is used as a leaf spray.
