Chemistry has become an inseparable part of our day to day lives. It’s in the food we eat, air that we breathe, chemicals used for cleaning, the emotions that are in almost every object surrounding us.
ONIONS MAKE US CRY
Everyone must have tried cooking. Cutting onions brings tears and caused burning to our eyes because of the vapors. It’s because while slicing onion, we break the cells, thus they release a chemical compound that causes tearing.
CHEMISTRY OF EMOTIONS
The chemical messengers, known as neurotransmitters are responsible our emotions, for example, love, envy, infidelity, and infatuation.
FLOATING OF ICE
Have you ever wondered why the ice floats? How difficult would it have been it ice sank?
The reason behind this is that the substance should be less dense or mass per unit volume is less. Because of this reason the pebble or piece of rock when tossed into the bucket with water in it, sink. Due to this only lakes and ponds freeze from top to bottom, which helps the fishes and aquatic animals survive during the cold weather.
Soaps are made up of the fatty acid salts of potassium and sodium element. The process involved in the making of soap is known as saponification.
Soaps are able to clean properly because of its emulsifying property.
Sunscreen creams also use chemistry to block or allow to pass the sunrays, in order to protect us from harmful skin diseases, sunburn etc. It combines chemically the organic and inorganic components to filer the rays so fewer rays are able to penetrate through that layer. Enhanced technology is Sunblock, that reflects the suns rays completely thus none reaches to our body. the particles like zinc oxide and titanium oxide help in the scattering of light. But it whiteouts the skin, you could easily tell who is using sunscreen and who is sunblock.
EFFECT OF BAKING SODA AND BAKING POWER
The chemistry behind the baking powder and soda effect is that they are added to food that is to be baked which is result produce carbon dioxide and causes them to rise.
HOW DOES THE FOOD GO BAD
The reason behind the food getting bad or smelly is the chain of chemical reactions that take place in the food kept for a long time. Fats turn rancid. Bacteria that grows inside it can make us sick. Similarly, water kept in plastic bottles may change in their taste, because of the chemicals they may absorb from their packaging.
