2. Chemistry of Emotions Whenever you are feeling happy, sad, ecstatic, relaxed, or stressed, there are many chemical reactions taking place in your body. It is because of the chemical messengers called neurotransmitters released in the brain that you can fall in love and cry rivers because of...
Learn about chemical reactions in everyday life. Understand there are many chemical reactions in everyday life and discover some examples of...
Clouds are a large-scale example of condensation, and generally form when water vapor in warm air rises to meet cold air higher in the atmosphere. As the warm air cools and the molecules coalesce and stick together, drops of water or ice crystals form and surround dust particles in the air...
Chemistry, though a mystery to many, is heavily involved in every aspect of our daily life. Our very existence depends upon it. There are numerous examples lying around- big and small, that can make us realize how vital chemistry is in everyday life. Let
Protein molecules are relatively big, containing hundreds of amino acids bound together into long chains. The chains are folded into compact globs, and these globs are held together by weak chemical bonds (non-covalent). When you apply heat to eggs, their molecules move faster and collide. As...
All organic, or living, things on Earth are made of carbon. Your organs, cells, and internal systems all depend on carbon to exist. Carbon has a unique structure that helps it to bond easily with other atoms and make up larger complicated molecules. This structure helps it play a fundament...
A material like rubber, on the other hand, is made of long-chain molecules (polymers) that are very weakly attached to one another; that's why raw, white, latex rubber is so stretchy and why black, vulcanized rubber (like that used in car tires) is harder and stronger, because heat-...
They're All Around Us Here are examples of organic chemistry at work: Polymers consist of long chains and branches of molecules. Common polymers you encounter every day are organic molecules. Examples include nylon, acrylic, PVC, polycarbonate, cellulose, and polyethylene. Petrochemicals are chemicals...
Chemistry is a big part of your everyday life. You find chemistry in foods, the air, cleaning chemicals, your emotions, and literally every object you can see or touch. Here are 10 examples of everyday chemistry. Some common chemistry might be obvious, but other examples might surprise yo...
