Vocab Words Flashcards
Graph
Visual representation illustrating how one variable changes with another variable , or it is a to used to illustrate the relationship between two variables.
Parallel lines
Two straight lines if they have identical slopes.
Gas molecules
Held together by intermolecular forces, no regular shape, rapid motion, posses KE.
Boiling point
Temperature at which vapor pressure of a liquid equals the atmospheric pressure.
Later heat of vaporization
Heat absorbed when a liquid vaporizes at normal boiling point.
Latent heat of fusion
Heat absorbed when a liquid vaporizes at normal boiling point
Heat of fusion
Heat required to increase the inter atomic or intermolecular distances in the crystal allowing melting.
Equilibrium of saturation solubility.
Maximum amount of a solute or drug that is present in the solution form per unit volume of a solvent at a constant temp and pressure.
Equilibrium condition
When the rate of transfer of a solid in to the solvent and a rate deposition of a solute molecule from the solvent on to the solid crystal become equal.
Solubility
Maximum among of a solute present in a solution form per unit volume of a solvent at constant temp and pressure following the attainment of equilibrium constant.
Dynamic equilibrium
Rate of vaporization and rate of condensation become equal at a definite temperate, become saturated,
Equilibrium vapor pressure
Pressure of saturated vapor above liquid.
Solubility of a substance
Quantity that will dissolve in a specified quantity of solvent to form a saturated solution at given temperature.
Saturated solution
Drug molecules in a solution are in equilibrium w/ excess of solute in a solution.
Supersaturated solution
Solution containing more of the dissolved solute than it would normally contain at a definite temperature.
