For each of the following cases, state whether the density of the object increases, decreases, or remains the same:
(d) An iron bar is cooled.



Answer :

The density of the iron bar when it is cooled - Increases.

  • Density is defined as the mass per unit volume or it is mass divided by volume.
  • Kilogram per cubic meter (kg/m³) is the SI unit of density.
  • The formula for density, d = m/V, where d is density, m is mass, V is volume
  • Density is a physical property because each substance has its own unique density.
  • It is an intensive property.
  • The reciprocal of the density of a substance is called specific volume.
  • It is the division of the mass of a substance and the volume of the substance.

When an iron bar is cooled, its density Increases.
