Aug 31, 2018 · The everyday use of our plastic and steel machines that take us from point A to point B is a huge example of chemistry that surrounds us. With the growing need to improve gas mileage, auto manufactures are continually innovating ways to incorporate lightweight materials for cars and trucks.
May 16, 2024 · In this article, we’ll explore some of the ways chemistry impacts our daily lives and examine 12 examples of chemistry in everyday life that you may have never considered.
Aug 15, 2015 · There are many examples of chemistry in daily life, showing how common and important it is. Digestion relies on chemical reactions between food and acids and enzymes to break down molecules into nutrients the body can absorb and use.
- Anne Marie Helmenstine, Ph.D.
- 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, can you name the other elements that make you?
- 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.
- Why Onions Make You Cry. They sit there so harmless-looking on the kitchen counter. Yet as soon as you cut an onion, the tears begin to fall. What is it in onions that makes them burn your eyes?
- Why Ice Floats. Can you imagine how different the world around you would be if ice sank? For one thing, lakes would freeze from the bottom. Chemistry holds the explanation for why ice floats while most other substances sink when they freeze.
- Combustion. You experience combustion reactions when you strike a match, burn a candle, start a campfire, or light a grill. In a combustion reaction, a fuel reacts with oxygen from air to produce water and carbon dioxide.
- Photosynthesis. Plants use a chemical reaction called photosynthesis to convert carbon dioxide and water into food (glucose) and oxygen. It’s a key reaction because it generates oxygen and yields food for plants and animals.
- Aerobic Cellular Respiration. Animals use the oxygen provided by plants to perform essentially the reverse reaction of photosynthesis to get energy for cells.
- Anaerobic Cellular Respiration. Organisms also have ways of getting energy without oxygen. Humans use anaerobic respiration during intense or prolonged exercise to get enough energy to muscle cells.
For a better understanding of the chemistry that is virtually everywhere around us, we have provided day-to-day examples in two sections. Firstly, examples of chemistry within our body and secondly, examples of chemistry that exist outside our body or occur around us.
