>0.5 mcm •visible in both ordinary and electric microscope •does not PASS THROUGH eg: enulsions, suspensions

•Is the science of the delivery of APIs to the target site to achieve the pharmacological effect. •The study of the physical and chemical of drugs and their dosage forms. •Application of physics and chemistry in the study of drugs.

Transfer of electrons

debye dipole- induced dipole

0.1 nm •visible only in ELECTRIC microscope •pass thru filter paper eg: cheese, butter

states that the total pressure in a mixture of gases is equal to the sum of the partial pressure of each gas

characteristics of molecules that form mesophase

NM + NM

•follows the shape of its container •definite volume •gliding motion

solubility of ionic crystals in water

describes the relationship between vapor pressure. and the absolute temperature of a liquid

this law states that the rate of diffusion of the gas and the speed of the gas molecules. are inversely proportional to the diffusion and effusion

independent of the amount of the substance in the system •temperature •pressure •density, SG, VG •viscosity •surface tension *unchanged

<0.1 nm •INVISIBLE •pass thru filter paper amd semi permeable membrabe

other term for mesophase

•thread like •rotate in 1 axis •mobile in 3 directions

•constant P •ISOBARIC •Linear

weak forces that involves the dispersion of charge across a molecule called a dipole

other gas law

heat absorbed by 1 mole of liquid when it passes into vapor state

exhibits properties intermediate between solids and liquids

only visible gas

physical properties of system

unequal sharing of electrons

a mixture of two or more components that form a honogenous molecular dispersion or one ohase system

most common gas laws

molecules or ions dispersed throughout the solvent

pressure of the saturated vapor above a liquid resulting from the escape of the surface liquid molecules

•special case •chiral nematic •higher opacity

•mariotte's law • constant T •ISOTHERMIC •non linear

van der waals forces

DEPENDENT of the amount of tye substances in the system •mass •length •volume *changed

•important in biological structures •ex.: mi celles and lipid bilayer membrane

london induced dipole-induced dipole

clad

types of mesophase

other physical properties

forces necessary to cohere and forces necessary to prevent molecular interpenetration "clad"

resposible for the LIQUEFACTION OF GASES is an aerosolized dosage form. •brings about condensation of non polar gas molecules

equal sharing of electrons

results from the tendency of molecules to align themselves with the oppositely charged end of their neighbor

keesom dipole-dipole

aloy formation

soap like or grease like •rotate in 1 axis •mobile in 2 directions

•amonton's law •constant v •ISOCHORIC •linear

polar molecules can produce temporary electric dipole in a non polar molecule

formation of iodide complex which accounts for solubility of iodine in Kl. test solution

uniquely strong hydrogen + fons accounts for the UNUSUAL PROPERTIES of water •high dielectric constant •high boiling point •low vapor pressure

the first recorded type of liquid crystal obtained through the application of heat

states that solubility of any gas increases as the external pressure is increased

classification of dispersed system

•fills available spaces •compressible •invisible •kinetic energy in rapid motion •weakest intermolecular forces

non metal + metal

M + M
