  PRACTICAL 18 To find the density of a liquid using 5 ml syringe (instead of density bottle). VIVA VOCE Q1: What is the aim of the experiment? A1: The aim of the experiment is to find the density of a liquid using a 5 ml syringe instead of a density bottle. Q2: What is the basic principle used to determine the density of a liquid in this experiment? A2: The basic principle involves measuring the mass of a known volume of the liquid and then calculating its density using the formula \( \rho = \frac{m}{V} \), where \( \rho \) is density, \( m \) is mass, and \( V \) is volume. Q3: Describe the procedure of the experiment briefly. A3: The procedure involves the following steps: 1. Weigh an empty 5 ml syringe. 2. Fill the syringe with the liquid up to the 5 ml mark. 3. Weigh the syringe filled with the liquid. 4. Calculate the mass of the liquid by subtracting the mass of the empty syringe from the mass of the filled syringe. 5. Calculate the density using the mass and the known volume (5

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

PRACTICAL 16 To study the relationship between load and extension (Helical spring) by drawing a graph. VIVA VOCE   Q1: What is the aim of the experiment? A1:The aim of the experiment is to study the relationship between load and extension in a helical spring by drawing a graph. Q2: What is Hooke's Law? A2:Hooke's Law states that the extension of a spring is directly proportional to the load applied to it, provided the elastic limit is not exceeded. Q3: How do you calculate the spring constant (k)? A3:The spring constant (k) is calculated using the formula \( k = \frac{F}{x} \), where \( F \) is the load applied and \( x \) is the extension produced. Q4: What is the elastic limit? A4:The elastic limit is the maximum load that a spring can bear without undergoing permanent deformation. Q5: Describe the procedure of the experiment briefly. A5:The procedure involves hanging the helical spring vertically, adding known weights incrementally, measuring the corresponding extensions, an
