What is meant by density What is its SI unit?
Density is defined as mass per unit volume. Hence its SI unit is: kg/m3.
Is density measured in kg?
Density is the mass per unit volume of a substance. The formula for density is: density = mass/volume. The unit for mass is kilograms (kg)/grams (g) and volume in centimetres cubed (cm3) or metres cubed (m3).
What is density in short answer?
Density is a characteristic property of a substance. The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). Density equals the mass of the substance divided by its volume; D = m/v.
What is the purpose of density experiment?
The purpose of this experiment is to understand the meaning and significance of the density of a substance. Density is a basic physical property of a homogeneous substance; it is an intensive property, which means it depends only on the substance’s composition and does not vary with size or amount.
How does density affect work?
Much as an object’s tendency to float or sink depends upon its density, so too does a person’s work density describe whether or not they will be satisfied. In the chart above, a very strong inverse relationship is noted between job satisfaction and work density (at the 0.01 alpha level).
What is an example of more dense?
Students should see that objects made of glass or metal tended to be denser than objects made from cardboard or paper. Objects that have a greater density than water will sink, whereas less dense objects will float.
How do you explain density to a child?
Density measures the mass of an object or substance compared to its volume. The equation we use to find density is: density = mass / volume. If an object is heavy and compact, it has a high density. If an object is light and takes up a lot of space, it has a low density.
What does a high density mean?
adjective. having a high concentration: entering a high-density market with a new product; high-density lipoprotein. Computers. (of a disk) having a large capacity for data storage: high-density DVDs.
What has the highest density?
osmium
