INTRODUCTION TO CHEMISTRY

INTRODUCTION TO CHEMISTRY Chemistry is a branch of Science. Science is basically the study of living and non-living things. The branch of science that study living things is called Biology. The branch of science that study non-living things is called Physical Science. Physical Science is made up of: (i) Physics– the study of matter in relation to energy (ii) Chemistry– the study of composition of matter. Chemistry is thus defined as the branch of science that deals with the structure composition, properties and behavior of matter. Basic Chemistry involves studying:   (a) States/phases of matter Matter is anything that has weight/mass and occupies space/volume. Naturally, there are basically three states of matter. (i) Solid-e.g. soil, sand, copper metal, bucket, ice. (ii) Liquid e.g. water, Petrol, ethanol/alcohol, Mercury (liquid metal). (iii) Gas- e.g. Oxygen, Nitrogen, Water vapour. A solid is made up of particles which are very closely packed. It thus… Read More »INTRODUCTION TO CHEMISTRY
