Characteristics of saturated vapour pressure Basically, the vapor pressure is the partial pressure of liquid vapor (e.g. water vapor). Saturated vapor pressure is the vapor…

Relation between water vapour and air pressure We know, if there is water vapour or if air is moist then its density also changes. Density…

Characteristics of unsaturated vapour pressure An unsaturated solution is when the solute can’t dissolve in the solvent. For example, if you have a glass of…

Degree of freedom Total number of independent or free motions that a body can have, these numbers are called degrees of freedom. It is an…

Unit of Pressure explanation with Example Molecules in air randomly and continuously move to and fro and consequently force applied by these molecules per unit…

Water Vapour and Air Pressure In atmosphere there always exists some water vapour. Through evaporation process enough water are evaporated from canals, ponds, water reservoir,…

Proof of Law of Equipartition of Energy The law of equipartition of energy states that for any dynamical system in thermal equilibrium, the total energy…

The Law of Equipartition of Energy Before discussing the law of equipartition of energy we need to know what is ‘degrees of freedom’. Degrees of…
