MATTER
Science interprets nature in terms of energy and matter. Matter, the material of which the universe is composed, may be defined as anything that has mass and occupies space. Mass is a measure of quantity of matter. The mass of a body which is determined by means of an analytical balance is invariable, while the weight of a body is not. Weight is the gravitational force of attraction exerted by the earth on a body. The weight of a given body varies with the distance of that body from the centre of the earth. The weight of a body is directly proportional to its mass as well as the earth’s…
INTRODUCTION TO CHEMISTRY
Chemistry may be defined as the science that is concerned with the composition and the structure of matter, and with the forces that hold the structures together. Chemistry as a science has, as its primary objectives, the determination of the nature and properties of the non-living matter, which surrounds us, and the preparation of new substances that are scientifically interesting, or generally useful from the materials which nature has provided. In trying to determine the nature of substances, it probes into principles governing the changes that matter undergoes, when subjected to conditions which they normally do not encounter, such as high temperature, high pressure, contact with other materials under different…
ETHICAL, LEGAL AND SOCIAL ISSUES IN CHEMISTRY
The study of chemistry has brought tremendous, positive development to the world and to Nigeria in particular. Chemistry has contributed greatly towards providing our basic needs and improving the quality of our life. For example, the provision of clothing, housing, better food and transportation is made possible through the knowledge of chemistry. However, there are some products of science (chemical wastes) that can cause havoc to the lives of plants and animals and the environment. WRONG APPLICATIONS OF SCIENCE (CHEMISTRY)Â Chemistry can be applied in a right way to bring about advantages and comfort to people. On the other hand, wrong application of chemistry in the area of chemical…
