CHEMISTRY IN EVERYDAY LIFE

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 add 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 add laboratories. It is all around us, the better we know chemistry, the better we know our world. Chemistry is present in every aspect of life, and its few examples are:  

    ow sunscreen works? 

Actually it combines organic and in organic chemicals to filter the light from sun So that less of it reaches the deeper layers of your skin. The reflective particles in the sunscreen usually consist of zinc oxide or titanium oxide. 

    ffee 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 signalled. 

     cry while cutting onions. 

Onions make you cry due to the presence of sulphur in the cells which break after the onions are cut. This sulphur gets mixed with the moisture and thus irritates your eyes. 

    getables 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.  

There are also some other examples like:  

# Ice float on water. 

# How soaps cleans? 

# Meals are cooked faster in pressure cooker. 

# The chemistry of love. 

# Sky is blue. 

 

Conclusion: Chemistry is an important part of our daily life. we see chemistry in our food we eat, soap we use, in our emotions and everything we see and touch. It is impossible to live without chemistry. Life is chemistry
