Question
Chapter 1, Problem 1.73SP
Interpretation Introduction
Interpretation:
The density of lithium cylinder of height
Concept introduction:
The density of any object is obtained when the mass of object in grams is divided by volume of an object in milliliters. So it is denoted by unit: gram per milliliter.
Density is directly associated to the mass of an object. The higher the mass of the substance higher will be its density. Density is inversely associated to the volume of a substance. The lower the volume of the substance higher will be its density.
Density is associated to how the particles are packed in a substance, which in turn determines its state. The state of a substance defines density. Solids are characterized by the highest and gases by the least density.
