In everyday life, the use of chemistry is evident in a person's environment; in the preparation of food, different household products and in the manufacture of cosmetic and pharmaceutical supplies. For example, the atmosphere, which humans need for life, is the composition of different elements like oxygen, nitrogen and hydrogen.Know More
Every day people use different household products like bleach, ammonia, soap and detergents. These products are all made through different chemical reactions. For example, the making of soap is a chemical reaction that requires the heating of fats or oils and causing a reaction with an alkali to produce soap and water. The process is called saponification.
The foods people prepare contain substances like baking soda and vinegar, which are examples of a base and acid, respectively. Salt, which is sodium chloride, is another substance used in cooking.
Likewise, the medications and drugs that people use are different pharmaceutical compounds made in a laboratory. The manufacture of textiles, plastics and cosmetic goods all involve the use of chemistry for their fabrication.Learn more about Chemistry
Biology is important to everyday life because it allows humans to better understand their bodies, their resources and potential threats in the environment. Biology is the study of all living things, so it helps people to understand every organism alive, from the smallest bacteria to California redwoods and blue whales. Professional biologists often concentrate on a small subset of living organisms, such as birds, plants or bacteria.Full Answer >

The number pi, represented by the symbol π, is used in everyday life to calculate the radius or circumference of circles and in design and construction. Pi is an irrational number, often approximated to 3.14, that was discovered by Greek mathematicians as a ratio to relate the diameter of a circle to the circumference.Full Answer >
Geometry is used in everyday life for building and construction, home decorating, outdoor projects and professional work. The geometric formulas for area and perimeter are often used to accomplish projects that require room and object measurements. For squares and rectangles, the area = base x height and the perimeter = base x 2 + height x 2.Full Answer >
