Using English To Give Evidance: Chemistry In Daily Live
We all are made of chemicals and everything around us is made of chemicals. Everything we hear, see, smell, taste, and touch involves chemistry and chemicals (matter). Hearing, seeing, tasting, and touching all involve intricate series of chemical reactions and interactions in our body. Many of the changes we observe in the world around are caused by chemical reactions. Chemistry is not limited to beakers and laboratories. It is all around us, and the better we know chemistry, the better we know our world. Chemistry is present in every aspect of life, and few examples are-
1. sky is blue - An object is coloured because of the light that it reflects. The white light from the sun contains all the wavelengths, but when it impacts on an object some of its wavelengths are absorbed and some reflected. The colour of the sky can be explained considering phenomena named Rayleigh scattering that consists on the scattering of light by particles much smaller than its wavelength. This effect is especially strong when light passes through gases.
2. Ice Float on water- Ice is less dense than liquid water. The heavier water displaces the lighter ice, so ice floats on top.
3. How Sunscreen Works?- Sunscreen combines organic and inorganic chemicals to filter the light from the sun so that less of it reaches the deeper layers of your skin. The reflective particles in sunscreen usually consist of zinc oxide or titanium oxide.
4. Meals are cooked faster in a pressure cooker? - A pressure cooker has a more elaborated lid that seals the pot completely. When we heat water it boils and the steam cannot escape, so it remains inside and starts to build up pressure. Under pressure, cooking temperatures raise much higher than under normal conditions, hence the food is cooked much faster.
5. The chemistry of love- Chemistry is at the bottom of every step in a relationship. When we fall in love, our brain suffers some changes and also certain chemical compounds are released. Love is driven by these hormones: oxytocin, vasopressin, endorphins.
6.
Coffee keeps us awake-
Coffee keeps us 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.
7. Vegetables are coloured- Many vegetables and fruits are strongly coloured because they contain a special kind of chemical compound named carotenoids. These compounds have an area called choromophore, which absorbs and gives off particular wavelengths of light, generating the colour that we then perceive.
8. How soap cleans?- Soap is formed by molecules with a ‘head’ which likes water (hydrophilic) and a long chain that hates it (hydrophobic). Then when soap is added to the water, the long hydrophobic chains of its molecules join the oil particles, while the hydrophilic heads go into the water. An emulsion of oil in water is then formed, this means that the oil particles become suspended in the water and are liberated from the cloth. With the rinsing, the emulsion is taken away.
9. We cry while cutting onions- 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.
what impact we much drink coffe?
BalasHapusEarly Death If you consume more than 4 cups of coffee per day, this is associated with premature death. A Mayo Clinic study partner found that men who drank more than four 8 fl.oz. Coffee cup increased 21% in all causes of death. "Coffee contains many active biologic compounds, including phenolic acids, potassium, and caffeine," said lead author Dr Erikka Loftfield of the National Cancer Institute in Rockville, Maryland. Coffee drinkers have a risk of death from heart disease, chronic respiratory illness, diabetes, pneumonia and influenza and suicide, but not cancer, researchers found. High blood pressure According to a study from Charalambos Vlachopoulos, MD, in the study, caffeine rapidly increased the stiffness of large arteries in people with high blood pressure. Sharp caffeine can increase blood pressure, even for individuals whose blood pressure is usually normal. Consuming caffeinated coffee can substantially increase your blood pressure, although some people are more sensitive to the effects of caffeine than others. Cholesterol Drinking too much coffee is known to increase serum and LDL cholesterol, an increase in cholesterol is believed to be caused by an oil called terpene found in coffee.
HapusCould you like to discribe this sulfur get mixed?
BalasHapus
BalasHapusIn the above post I am interested in love chemistry, whether the same reaction when falling in love and breaking up love, please explain!
Based on research, there is a compound that is initiated in the human body when a person is in love. This compound could be one of the factors in household harmony and happiness of life. One of the compounds is phenylethylamine. Another compound is the "happiness hormones" responsible for all the upset of humans when falling in love is:
Hapus* Pheromones: make a crush on someone, make ngelamunn .. and imagine him continue
* Oxytocin: make kangennn, want to see the person banya ajah-liat doang few seconds
* Vasopressin: make faithful, "you know you are the only one .."
* Norepinephrine: make the spirit, hepi, cheerful, happy, want to smile continues, so the more canti / handsome
The chemicals explain our behavior as we begin to fall in love. These chemicals travel to parts of the brain that regulate our emotions and memory:
* Dopamine Say I'm Crazy About You
In the first few months when you have a crush on someone, there is a part of your brain that releases this substance. Even if the amount of this substance is just a little, that's enough to give you the sense of flying you feel when you're in love.
How sunscreens can combine organic and inorganic chemicals to filter light from sunlight
BalasHapusSunscreen (sunscreen or sunblock) or UV filter, has 2 main mechanism that is:
HapusA. Absorb energy of UV light. Turn it into a form of heat energy. Generally, organic UV filter compounds belong to this group.
B. Dissipate and reflect UV light energy.
Generally UV compounds of inorganic filters are included in this group. For example titanium dioxide, zinci oxide etc. Very many sunscreens contain ingredients that work with both of these mechanisms known as UV protection. Currently UV protection is used in conjunction with daily-used products, such as moisturizing creams and hair care products, aftershave products, lipsticks or make-up products. UV protection can be classified into 2 groups based on their origin. Inorganic UV protection, also called UV physical protection, mainly works by reflecting and scattering UV radiation, organic UV protection, also called UV chemical protection or sunblock, works by absorbing radiation.
Why on making soap the role of oil is very important?
BalasHapusBecause oil has high lauric and myristic acid content and can make soluble soaps and foamy.
HapusExplain what are the benefits of chemicals in everyday life?
BalasHapusMany kinds of chemicals that exist in everyday life. Some groups of chemicals in question, among them are:
Hapus1. cleaners;
2. bleach clothes;
3. fragrances;
4. pesticides;
1. Cleaners In everyday life, we are familiar with various cleaning chemicals, including soaps and detergents. The type of chemicals that can be used as a cleanser include:
- body cleansers,
- hair cleaners,
- motor and car cleaners,
- plate cleaners,
- clothes cleaners,
- floor cleaners
2. Bleach
Bleach is usually sold in the form of a solution and is used to remove impurities or colored stains are difficult to remove by using only soap or detergent. Bleach solutions sold on the market usually contain sodium hypochlorite (NaOCl) active ingredients of about 5%. Besides being used as bleach and cleaning stains, it is also used for disinfecting (disinfecting germs). In general, whitening agents sold on the market are safe to use during use in accordance with the instructions. In addition to the stain, this substance can also react with the dye clothes so that it can fade the color of clothing. Therefore, the use of this bleach should be as directed.
3. Fragrance
Perfume is another chemical that closely related to our daily life. We can obtain deodorant from both natural and synthetic materials. In addition to substances that give rise to fragrance, fragrances sold on the market usually contain other substances, such as alcohol for liquid perfumes and alum for fragrance-shaped solids.
4. Pesticides
Chemical types of pesticides are very close to the life of farmers. Pesticides are used to eradicate plant pests so as not to disrupt agricultural production. Pesticides commonly used by farmers can be classified according to the function and target of its use, namely:
A. Insecticides, namely pesticides used to eradicate insects, such as grasshoppers, ladybirds, aphis, and caterpillars.
B. Fungicide, a pesticide used to eradicate and prevent the growth of mold or fungus.
C. Bactericide, ie pesticides to eradicate bacteria or viruses.
D. Rodenticide, a pesticide used to eradicate plant pests in the form of rodents, such as rodents.
E. Herbicides, ie pesticides used to eradicate weeds (weeds), such as reeds, grasses, and water hyacinths.
