Question

Define (i) density (ii) latent heat of fusion (iii) sublimation​

Answer 1

HERE IS UR ANSWER MATE!!!!

(i) DENSITY:

the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: where ρ is the density, m is the mass, and V is the volume.

(ii) LATENT HEAT  OF FUSION:

Latent heat of fusion is the change in enthalpy of any amount of substance when it changes from solid state to liquid state. The temperature at which this occurs is known as the melting point of that substance. ... For example, the latent heat of fusion for water (ice) is about 334 kJ/mol.

(iii) SUBLIMATION:

Sublimation is a type of phase transition, or a change in a state of matter, just like melting, freezing, and evaporation. Through sublimation, a substance changes from a solid to a gas without ever passing through a liquid phase. Dry ice, solid CO2, provides a common example of sublimation.

HOPE THIS HELPS U!!!!!!!

Answer 2

DENSITY:
mass occupied by a solid bird unit volume and is obtained by dividing the mass of a particular solid by the volume occupied by the mass of the solid .
density = mass / volume.
the unit of density is kg/l or kg /dm

LATENT HEAT OF FUSION:the amount of heat energy that is needed to convert 1 kg of solid into the liquid state at its melting point temperature without any rising temperature under atmospheric pressure .

SUBLIMATION:the change of solid directly into the gaseous state without passing through the liquid state upon heating .
example of sublimation:naphtalene balls ,camphor,iodine,ammonium chloride are some common examples of the substances which undergo sublimation
