“Elements and the classification of elements” is a beginner’s guide to the fundamental building blocks of everything around and within us. Introduction Take a deep breath! The air you are inhaling is full of elements—oxygen, nitrogen, even a bit of argon. They are invisible, but they are everything. However, not all elements are invisible, for […]

The 2 types of letters — formal letter vs informal letter — have served as essential forms of communication for centuries. Introduction In a world driven by communication, writing the right kind of letter matters. Whether you are applying for a job or writing to a friend abroad, or writing in an examination setting, the

As a starting point, it is important to describe the 3 main characteristics of a computer as a system and how it interacts with its environment. Introduction Have you ever thought of your computer as a living system — kind of like a person? We, as a human being, have a brain to think, memory

The observable universe gives us smooth access to 3 fundamental states of matter — solid, liquid, and gas — along with plasma. These four states form the core of countless functions and actions in our everyday lives. Introduction Previously, we have talked about matter, the classification of different states of matter, and their types based

To examine the relationship between systems and different branches of science, it is important to understand how different systems work and how they are created. Introduction Science allows us to understand the world around us and helps us to develop systems that solve our problems. The systems that we encounter are either natural (like galaxies,

Understanding the difference between atmospheric pressure and hydrostatic pressure and the ways of measurement of atmospheric pressure and hydrostatic pressure is crucial in physics. Introduction Pressure is a fundamental concept in physics. From the weather we experience to how we breathe, it affects our daily lives in ways we often do not notice Tail a

Here, we shall learn the answer to “What is pressure in physics?” and “How pressure is measured in different states of matter i.e. solid, liquid, and gas?” Besides, we shall also learn about types of pressure, real-life applications, and the science behind it. Introduction From the way air keeps airplanes aloft to how submarines dive,

In classical mechanics, the law of conservation of energy derivation and the concept of interconversion of potential energy and kinetic energy form the bedrock of how we analyse physical systems. Introduction The law of conservation of energy is also known as the principle of conservation of energy. This principle is essential across physics, engineering, biomechanics,

Understanding systems becomes even more meaningful when we look at the 2 major types of systems: natural systems and artificial systems. Each has its characteristics, examples, and areas of use. Introduction Every system tells a story—some written by nature, others engineered by human hands. From the tiniest cell to the largest satellite network, systems shape

For starters, to define and describe the concept of a system is important. The reason is that the theory of systems helps us understand; Introduction In a nutshell, a system is comprised of different components. For instance, a car has multiple parts like the engine, power transmission mechanism, wheels, brakes, etc. Each part of the
