Introduction Every matter in the universe is composed of tiny particles called molecules. They attract each other with some attractive force. There exists an intermolecular force of attraction between molecules. The matter is classified into five categories based on the force of attraction between the molecules. They are solid, liquid, gas, plasma, and Bose-Einstein. Solids…

Introduction Buoyancy is the upward force exerted on an object that has been immersed in the fluid. The fluid can be water, another liquid, or even gas, as long as it cannot penetrate the solid object fully. This upward force on the object is referred to as buoyant force or buoyancy and can be calculated…

Introduction Archimedes’ Principle is an important principle of fluid mechanics. It is discovered by a Greek mathematician and scientist Archimedes. This principle is utilized to estimate the volume of an object that has an irregular shape, density, and distinct gravity of an object. What is Archimedes’ Principle? A body placed on a fluid (liquid or gas)…

Introduction According to physics, different real-life applications of specific gravity are available. In the practice, specific gravity does not include any dimensionless quantity that has the correct implications. Measuring specific gravity needs to take the consideration of the refractive index scale, and the right scale is marked with the scale of g/100ml. Moreover, pressure also…
