• Which is more denser 1-kg of feathers or 1-kg of lead ? • both have the same density . • Density =Mass/volume. • The SI unit of density is =KG/M3 or G/CM3. • Mass/unit volume EG: water-1.0g/CM3 ,ice-0.92g/CM3,gold-19.3g/CM3,alumium-2.7g/CM3 • So Lead is more denser than air in g/cm3 because the particles in air are spread and fair apart from each other, but lead is a solid and it's particles are packed closely together and each particles has more mass than a particle of air .

Idea Of Density

in Aswajith

Which is more denser 1-kg of feathers or 1-kg of lead ?
both have the same density .
Density =Mass/volume.
The SI unit of density is =KG/M3 or G/CM3.
Mass/unit volume EG: water-1.0g/CM3 ,ice-0.92g/CM3,gold-19.3g/CM3,alumium-2.7g/CM3
So Lead is more denser than air in g/cm3 because the particles in air are spread and fair apart from each other, but lead is a solid and it's particles are packed closely together and each particles has more mass than a particle of air .

1.Definition of density.

2. Application of density in real life.state few.

3. How we will know if a substance is less dense than water?

4. Is density a scalar or vector quantity?

5. When ice melts,what happens to its density?

Replying to

Density is mass/unit of volume .
construction, cooking ,boats, water tanks , environment science.
If the substance is more denser than water it will sink , If the substance is less denser than water it will float. It can be also find by looking, is the substance's mass/unit of volume is greater than water's mass/unit of volume it will sink.
It has no direction so it is a scalar quantity.
when ice melts it's density increases because water is more denser than solid ice
