(a)
Interpretation: The behavior of atoms/ions during the faster cooking with hot water in a pressure cooker than in an open pan needs to be explained.
Concept Introduction: Colligative properties are the properties of solution which depend on the number of particles present in the solution. Some common examples of colligative properties are depression in freezing point, elevation in boiling point, osmotic pressure, lowering in vapor pressure etc. The number of particles is shown with the help of Van’t Hoff factor ‘i’.
The mathematical expression for depression in freezing point and elevation in boiling point are as given below:
(b)
