What Is Chemistry
What is Chemistry?
Chemistry is the study of matter and energy and the interactions between them. This is also the definition for physics, by the way. Chemistry and physics are specializations of physical science. Chemistry tends to focus on the properties of substances and the interactions between different types of matter, particularly reactions that involve electrons. Physics tends to focus more on the nuclear part of the atom, as well as the subatomic realm. Really, they are two sides of the same coin. * A science that deals with the structure, composition and properties of items and with the transformations that they undergo - the composition and chemical properties of a substance - chemical processes and phenomena (as of an organism) - a strong mutual attraction, attachment, or sympathy.
Why study chemistry?
Because understanding chemistry helps you to understand the world around you. Cooking is chemistry. Everything you can touch or taste or smell is a chemical. When you study chemistry, you come to understand a bit about how things work. Chemistry isn't secret knowledge, useless to anyone but a scientist. It's the explanation for everyday things, like why laundry detergent works better in hot water or how baking soda works or why not all pain relievers work equally well on a headache. If you know some chemistry, you can make educated choices about everyday products that you use. Chemistry is a big part of your everyday life. You find chemistry in daily life in the foods you eat, the air you breathe, your soap, your emotions and literally every object you can see or touch. Here's a look at some everyday chemistry:
Uses of Chemistry:
Over the last two centuries, chemistry has changed our daily lives more than any other of the sciences. Chemistry makes our world more colorful, more efficient, more reliable and safer. Pharmaceuticals, cosmetics, toiletries and body care products, airbags and brake fluid - they're all chemical products. in cooking use
