shote note on density
Answers
Answer :-
Density is a measure of how compact the mass in a substance or object is. The density of an object or substance can be calculated from this equation: density in kilograms per meter cubed is equal to mass in kilograms, divided by volume in meters cubed. Or in other words, density is mass spread out over a volume.
Density is a measure of mass per unit of volume.
The mass of a unit volume of a substance is called its density.
Relative density of a substance is defined as the ratio between the density of the substance to the density of the water at 40 C. Relative density is also known as specific gravity. The relative density of a substance is a pure number without any unit.
Density is important because it affects whether object will float or sink. It is an important property to consider when building things like ships and hot air balloons. He lies that the amount of water that spilled was equal in volume to the space that his body occupied.
The average density of an object equal to its total mass divided by its total volume.
An object made from comparatively dense material (such as iron) will have less volume than the object of equal mass made from some less dense substance (such as water).
Perhaps the highest density known is reached in neutron star matter.
The singularity at the centre of a black hole, according to general relativity, not have any volume, so its density is undefined.
Density measurement is used to specify and describes a pure substance but also determines concentrations of binary mixtures and therefore gives information about the composition of mixture. It is, for example, useful during quality control or helps determine the feeling volume during the bottling of a product.
The density of an object is the mass of the object compared to its volume. The equation for density is:
Density = Mass/Volume
OR
D = m/v
Each substance has its own characteristic density because of the size or mass and arrangement of atoms or molecules.
DENSITY is a physical property of matter as each element and compound has a unique density associated with it. Density defined in a qualitative manner as the measure of the relative heaviness of objects with the constant volume. If an object such as a piece of wood floats on water it is less dense than water.
Hope this help u!!!!
