BVapour pressure of solution increases because more mumber of molecules of liquids A and B can escape from the solution. Cvapour pressure of solution decreses because less number of molecules of only one of the liquids escape from the solution. DA-B interactions are weaker than those between ...
The vapour pressure of the four-phase equilibrium: solid Pb (NO3)2-solid NH4,NO3-saturated aqueous solution-water vapour, was measured from 10° C to the end-point of the four-phase curve. That end-point is the eutectic point of the binary system Pb (NO3)2-NH4NO3. This eutectic point...
Vapour Pressure of Liquid Solutions: A solution is formed when a solute is dissolved in a solvent. The solvent is generally a liquid. The solute can be a solid, liquid or gas. Additionally, a solution may contain one or more volatile components. Generally, the solvent which is in a ...

To find the vapor pressure of the solution formed by mixing 2 moles of liquid A and 3 moles of liquid B, we can use Raoult's Law. Here are the steps to solve the problem:Step 1: Identify the given data - Vapor pressure of pure

The pulmonary deposition of99mTc-labelled hexamethyl propylene amine oxime, used as a model for propellant soluble drugs, was studied in healthy volunteers using gamma scintigraphy. The radiolabel was delivered using a metered dose inhaler using a low vapour pressure chlorofluorocarbon fill (LVPA, 255...
In other words, that the vapour pressure near a very thin film may be less than it can be near a thick one at the same temperature. It is evident that inside or outside a solid box stability must be possible, so that the second alternative is the only solution....
The BARTEC BENKE RVP-4 Vapour Pressure Process Analyser measures the vapour pressure of a variety of petroleum products. This unit features an ASTM compliant cylinder piston design with 4:1 expansion, an integral temperature control unit and network and fieldbus communication...
Properties such as boiling point, freezing point, and vapour pressure of a pure solvent change when solute molecules are added to get homogeneous solution. These are called colligative properties. Applications of colligative properties are very useful in day-tөday life. One of the examples is ...
