Concept explainers
a)
Interpretation:Simple distillation should be defined.
Concept introduction: Distillation is a technique that is used to separate components of liquid mixture with the help of selective boiling and condensation. This procedure either separates components partially or completely from the mixture. It is one of the physical processes to separate mixtures and not by
b)
Interpretation: Head temperature should be defined.
Concept introduction: Conversion of substance from its liquid to vapor state is called boiling. The boiling point is the temperature that has a vapor pressure of liquid equal to pressure that is present around liquid.
c)
Interpretation: Pot temperature should be defined.
Concept introduction: Conversion of substance from its liquid to vapor state is called boiling. Boiling point is the temperature that has a vapor pressure of liquid equal to pressure that is present around liquid.
d)
Interpretation: Raoult’s law should be defined.
Concept introduction: Vapor pressure is known as the pressure of vapor that exists in equilibrium with its liquid or solid-state. In other words, it is the equilibrium pressure of vapor over its liquid or solid-state. It depends on the temperature of system.
e)
Interpretation: Ideal solution should be defined.
Concept introduction: Solution has two components. Out of these two components, one that is present in a larger amount is called solvent while that present in smaller amounts is known as solute.
f)
Interpretation: Dalton’s law should be defined.
Concept introduction: Vapor pressure is known as the pressure of vapor that exists in equilibrium with its liquid or solid-state. In other words, it is the equilibrium pressure of vapor over its liquid or solid-state. It depends on the temperature of the system.
