Introduction Energy is the capacity to do work. It exists in various forms such as potential energy, kinetic energy, mechanical energy, heat energy, and electrical energy. In nature and in machines, energy continuously changes from one form to another. The Law of Conservation of Energy states that energy can neither be created nor destroyed; it … Read more
Introduction: Conservation of Energy Energy is the ability to do work or cause change. It exists in many forms such as mechanical energy, heat energy, light energy, electrical energy, and chemical energy. In our daily life, we constantly observe energy changing from one form to another. The Law of Conservation of Energy states that energy … Read more
Introduction Water is one of the most important natural resources on Earth. All living organisms—humans, animals, and plants—depend on water for survival. However, in many parts of the world, water scarcity is becoming a major problem. Rapid population growth, climate change, urbanisation, and overuse of groundwater have increased pressure on our water resources. Therefore, we … Read more
