PRACTICAL 17 To find the density of a body heavier than water by Archimedes principle. VIVA VOCE   Viva Questions and Answers for Finding Density Using Archimedes' Principle Q1: What is the aim of the experiment? A1: The aim of the experiment is to find the density of a body heavier than water using Archimedes' principle. Q2: What is Archimedes' principle? A2: Archimedes' principle states that when a body is fully or partially submerged in a fluid, it experiences an upward buoyant force equal to the weight of the fluid displaced by the body. Q3: How do you determine the volume of the body using Archimedes' principle? A3: The volume of the body is determined by measuring the volume of water displaced when the body is submerged in water, which is equal to the volume of the body. Q4: Describe the procedure of the experiment briefly. A4:The procedure involves weighing the body in air, then submerging it in water and measuring the apparent loss in weight. The volume of t

πŸ‘‡ Answer copy of worksheet in the endπŸ‘‡   Introduction: Have you ever wondered how to create a mesmerizing rainbow effect right in your own kitchen? The "Rainbow in a Glass" activity is a delightful and educational experiment that allows you to layer different liquids with varying densities, resulting in a stunning display of colors. In this blog post, we will explore the science behind this activity and uncover the fascinating principles of density at work. Understanding Density: Before we delve into the activity itself, let's first grasp the concept of density. Density refers to how closely packed the particles in a substance are. It is determined by dividing the mass of an object by its volume. Essentially, density determines whether a substance will sink or float when placed in another substance. Materials Required: To embark on this colorful journey, you will need the following materials: - Clear glass or transparent container - Sugar syrup - Water - Vegetable oil -
