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…
