Question

define density. If the volume of object decreases, whether it's density will increase or decrease​

Answer 1

Answer:

This variation is typically small for solids and liquids but much greater for gases. Increasing the pressure on an object decreases the volume of the object and thus increases its density. Increasing the temperature of a substance (with a few exceptions) decreases its density by increasing its volume.

Answer 2

Answer:

Density = Mass/Volume

Explanation:

If volume increases density decreases, since density is inversely proportional to volume and mass is directly proportional to the mass.

Density:

It is a scalar quantity and is represented by the latter ρ (rho) or d.

In S.I system, unit of mass is kg and unit of volume is m³, so S.I unit of density is Kg/m³. In C.G.S it will be g/cm³.

Relationship b/w S.I and C.G.S units:

1 kg/m³ = 1 kg/1m³ = 1000g/(100cm)³

⇒ 1/1000 g/cm³

Thus,

⇒ 1 kg/m³ = 10^-3 g/cm³

⇒ 1 g/cm³ = 1000 kg/m³
