What is the branch of science that deals with matter energy and their relationship to each other

Most experiments include observations of small, well-defined parts of the natural universe designed to see results of the experiments. Why do we have to do experiments?

Chemistry as a Science

Why do we have to test? Because the natural universe is not always so obvious, experiments are necessary. For example, it is fairly obvious that if you drop an object from a height, it will fall. Several hundred years ago coincidentally, near the inception of modern science , the concept of gravity explained that test.

However, is it obvious that the entire natural universe is composed of only about fundamental chemical building blocks called elements?

Fields of study

In fact, the concept of the element is only about years old, and the last naturally occurring element was identified about 80 years ago. It took decades of tests and millions of experiments to establish what the elements actually are. These are just two examples; a myriad of such examples exists in chemistry and science in general.

When enough evidence has been collected to establish a general principle of how the natural universe works, the evidence is summarized in a theory. A theory is a very powerful statement in science. When written in this way, theories indicate that science has an overwhelming amount of evidence of its correctness. We will see several theories in the course of this text. A specific statement that is thought to be never violated by the entire natural universe is called a law.

A scientific law is the highest understanding of the natural universe that science has and is thought to be inviolate. For example, the fact that all matter attracts all other matter—the law of gravitation—is one such law. Here again, science uses these terms differently, and it is important to apply their proper definitions when you use these words in science.

What is the natural universe? Stars; planets; the appearance of life on earth; and how animals, plants, and other matter function are all part of the natural universe. Science is concerned with that—and only that. Of course, there are other things that concern us. For example, is the English language part of science? Most of us can easily answer no; English is not science. Think of it: the word spelled b-l-u-e represents a certain color, and we all agree what color that is.

But what if we used the word h-a-r-d-n-r-f to describe that color? See Figure 1. That would be fine—as long as everyone agreed. Anyone who has learned a second language must initially wonder why a certain word is used to describe a certain concept; ultimately, the speakers of that language agreed that a particular word would represent a particular concept. It was contrived. How would you describe this color? Blue or hardnrf?

It is very important in society. Science deals only with what occurs naturally. The field of science has gotten so big that it is common to separate it into more specific fields. First, there is mathematics, the language of science. All scientific fields use mathematics to express themselves—some more than others. Physics and astronomy are scientific fields concerned with the fundamental interactions between matter and energy. Chemistry, as defined previously, is the study of the interactions of matter with other matter and with energy.

Biology is the study of living organisms, while geology is the study of the earth. Other sciences can be named as well.

  8. Understand that these fields are not always completely separate; the boundaries between scientific fields are not always readily apparent. Therefore, a scientist may be labelled a biochemist if he or she studies the chemistry of biological organisms. Finally, understand that science can be either qualitative or quantitative. For example, physical properties are generally qualitative descriptions: sulfur is yellow, your math book is heavy, or that statue is pretty.

    As such, some quantitative descriptions would include 25 students in a class, pages in a book, or a velocity of 66 miles per hour. Quantitative expressions are very important in science; they are also very important in chemistry. Identify each statement as either a qualitative description or a quantitative description. Some of the simple chemical principles discussed in this chapter can be illustrated with carbonated beverages: sodas, beer, and sparkling wines. Each product is produced in a different way, but they all have one thing in common.

    8. They are solutions of carbon dioxide dissolved in water. Carbon dioxide is a compound composed of carbon and oxygen. Under normal conditions, it is a gas. If you cool it down enough, it becomes a solid known as dry ice. Carbon dioxide is an important compound in the cycle of life on earth. Even though it is a gas, carbon dioxide can dissolve in water, just like sugar or salt can dissolve in water. When that occurs, we have a homogeneous mixture, or a solution, of carbon dioxide in water.

      However, very little carbon dioxide can dissolve in water. If the atmosphere were pure carbon dioxide, the solution would be only about 0. In reality, the air is only about 0. However, when soda and beer are made, manufacturers do two important things: they use pure carbon dioxide gas, and they use it at very high pressures. With higher pressures, more carbon dioxide can dissolve in the water. When the soda or beer container is sealed, the high pressure of carbon dioxide gas remains inside the package. Of course, there are more ingredients in soda and beer besides carbon dioxide and water.

      When you open a container of soda or beer, you hear a distinctive hiss as the excess carbon dioxide gas escapes. But something else happens as well. The carbon dioxide in the solution comes out of solution as a bunch of tiny bubbles. These bubbles impart a pleasing sensation in the mouth, so much so that the soda industry sold over billion servings of soda in the United States alone in Some sparkling wines are made in the same way—by forcing carbon dioxide into regular wine.

      Physics and Religion Orderliness of systems in the universe can be traced back to the Creator. Many wonders of creation include the anomalous expansion of water, the rainbow. Physics and Geography Accurate use of instruments and physics concepts can establish weather patterns and explain formation of rainfall, pressure variations. Use of magnetic properties of lodestone and other materials help navigators to determine direction.

      Physics and Technology. Some areas of technology that requires knowledge of physics are: In medicine. X-rays, lasers, scanners which are applications of physics are used in diagnosis and treatment of diseases. Satellite communication, internet, fibre optics are applications of internet which requires strong foundation in physics. In the area of defense, physics has many applications e.

      In entrainment industry, knowledge of physics has use in mixing various colours to bring out the desirable stage effects. What is physics? Physics is the branch of science which deals with matter and its relation to energy. Under this branch, we look into details the aspects of linear, circular and oscillatory motions as well as motion of fluids ii Geometrical Optics This branch takes a keen look at the behavior of light in various media. Many physics formulae are expressed mathematically.

      Physics formulae are used in calculation of magnification by microscopes. The knowledge of levers helps to explain locomotion in Biology. Physics and Chemistry. Physics has helped in explaining forces within atoms and therefore atomic structure. It is this structure of the atom that then determines the reactivity of the atom as explained in chemistry. In industrial applications In the area of defense, physics has many applications e. At University level, some of the courses are offered. Bachelor of Architecture. Bachelor of pharmacy.
