Physical Pharmacy 2 Marks
-
What is matter?
Matter is anything which occupies space and has mass. -
Define solid, liquid and gases.
Solid: Matter which has definite shape and volume.
Liquid: Matter which has definite volume but no definite shape.
Gas: Matter which has neither definite volume nor definite shape. -
What is latent heat of vaporization?
It is the amount of heat required to convert 1 gm of liquid into vapour at its boiling point without change in temperature. -
Define boiling point.
The temperature at which the vapour pressure of a liquid becomes equal to the atmospheric pressure is called boiling point. -
What is triple point?
The temperature at which the solid, liquid and vapour forms of a substance co-exist in equilibrium is called triple point. -
Define vapour pressure.
The pressure exerted by the vapour of a liquid in a closed container is called vapour pressure. -
What is sublimation?
The conversion of solid into vapour without passing through liquid state is called sublimation. -
Define polymorphism.
The ability of a substance to exist in more than one crystalline form is called polymorphism. -
What is solubility?
The amount of solute dissolved in a specific quantity of solvent at a given temperature is called solubility. -
Define ideal solution.
An ideal solution is one in which there is no change in volume or heat when two substances are mixed. -
What is Raoult’s Law?
It states that the partial vapour pressure of a component in a solution is equal to the vapour pressure of the pure component multiplied by its mole fraction in the solution. -
Define surface tension.
It is the force per unit length existing at the interface between two immiscible phases. -
What is interfacial tension?
It is the tension at the interface of two immiscible liquids. -
Define adsorption.
The accumulation of molecules or ions on the surface of a substance is called adsorption. -
What is desorption?
The removal of adsorbed substance from the surface is called desorption. -
Define surfactants.
Compounds that lower the surface or interfacial tension are called surfactants. -
What is HLB?
HLB (Hydrophilic-Lipophilic Balance) is the relative degree to which a surfactant is hydrophilic or lipophilic. -
Define emulsion.
A biphasic system consisting of two immiscible liquids one of which is dispersed as globules in the other is called emulsion. -
What is sedimentation?
The settling down of particles under gravitational force is called sedimentation. -
Define rheology.
The study of flow and deformation of matter is called rheology. -
What is Newtonian flow?
Flow in which the rate of shear is directly proportional to shear stress is called Newtonian flow. -
Define non-Newtonian flow.
Flow in which the rate of shear is not directly proportional to shear stress is called non-Newtonian flow. -
What is thixotropy?
It is the property of certain gels or fluids that are thick under static conditions but flow when agitated. -
Define diffusion.
The process of intermingling of molecules of two or more substances is called diffusion. -
What is Fick’s first law?
It states that the rate of diffusion is directly proportional to the concentration gradient. -
Define dissolution.
The process by which a solid substance solubilizes in a given solvent is called dissolution. -
What is Noyes-Whitney equation?
It is an equation that describes the rate of dissolution of solids in liquids. -
Define partition coefficient.
It is the ratio of concentrations of a compound in a mixture of two immiscible solvents at equilibrium. -
What is pharmaceutical buffer?
A solution that resists change in pH upon addition of small quantities of acid or base is called buffer. -
Define isotonic solution.
A solution having the same osmotic pressure as that of body fluids is called isotonic solution.
What is hypotonic solution?
A solution having less osmotic pressure than body fluids is called hypotonic solution.What is hypertonic solution?
A solution having more osmotic pressure than body fluids is called hypertonic solution.Define buffer capacity.
It is the efficiency of a buffer solution to resist change in pH.What is solubility product?
It is the product of concentration of ions in saturated solution each raised to the power of its coefficient in balanced equation.Define common ion effect.
The decrease in solubility of a salt by the addition of a common ion is called common ion effect.What is complexation?
The association of two or more molecules to form a complex is called complexation.Define pharmaceutical aerosols.
Pharmaceutical aerosols are dosage forms containing therapeutically active ingredients dissolved or suspended in a propellant and intended to be administered as a spray.What is colloidal dispersion?
A system in which particles of colloidal size are dispersed in a continuous phase of different composition or state is called colloidal dispersion.Define suspension.
A coarse dispersion in which insoluble solid particles are dispersed in a liquid medium is called suspension.What is DLVO theory?
A theory that explains the stability of colloidal dispersions by balancing van der Waals attraction and electrostatic repulsion.Define zeta potential.
The potential difference between the dispersion medium and the stationary layer of fluid attached to the dispersed particle is called zeta potential.What is Brownian movement?
The continuous random motion of colloidal particles is called Brownian movement.Define Tyndall effect.
The scattering of light by colloidal particles is called Tyndall effect.What is micelle?
An aggregate of surfactant molecules dispersed in a liquid colloid is called micelle.Define critical micelle concentration (CMC).
The concentration of surfactants above which micelles are formed is called CMC.What is pharmaceutical powder flow?
It refers to the ability of powder to flow in a consistent and reproducible manner from a container.Define angle of repose.
It is the maximum angle formed between the surface of a pile of powder and the horizontal plane.What is bulk density?
It is the mass of powder divided by the bulk volume it occupies.Define tapped density.
It is the ratio of the mass of a powder to the volume it occupies after being tapped.What is Carr’s index?
It is a measure of compressibility of a powder.
