What happens to the volume, mass, and density of most solids as their temperature increases?

When the temperature of most of the solids is increased, their volume is also increased.

But their mass remains constant because volume change does not affect the mass of the solid.

The density of solids will change because of volume change.

As density = mass/ volume.

According to the above equation volume and density are inversely proportional.

So increase in volume and constant mass will decrease the density of solid.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
