The kinetic theory of gases begins with some basic assumptions depending on the behavior of gas molecules. These assumptions are called the postulates of the kinetic theory of gases which are summarized below. Postulates of Kinetic Theory of Gases Questions Based on the Postulates of Kinetic Theory of Gases The following types of questions may […]
Difference Between Lyophobic and Lyophilic Colloids
Depending upon the solvent affinity, the colloids are classified into two categories. Lyophobic Colloids or Sols: Lyophobic colloids are those colloids that have no spontaneous tendency to pass into the colloidal state and are obtained with difficulty. Lyophobic Colloids or Sols are also called hydrophilic when the dispersion medium is water. For example, metal sulfides, […]
Difference Between True Solution, Colloidal Solution and Suspension
In this article, differences between true solution, colloidal solution, and suspension are discussed with examples. Difference Between True Solution, Colloidal Solution, and Suspension In the following table, differences between True Solution, Colloidal Solution, and Suspension are given depending on particle size, osmotic pressure, visibility, examples, and more. True Solution Colloidal Solution Suspension The solute particles […]
Why is Internal Energy a State Function?
The internal energy (U) is a state function i.e., when a process occurs, the change in its value depends only upon its initial state and final state and is independent of the path by which the change is brought about. For example, let us consider a system having a particular pressure, volume, and temperature is represented by […]
