The temperature of a liquid decreases as it

WebTemperature: If temperature increases then the surface tension of a liquid decreases. (i.e., T ∝ 1/St) Soluble Impurities: In the case of less soluble impurities, the surface tension decreases. But, for highly soluble impurities in the liquid the surface tension increases. For small temperature differences, the variation in surface tension ...

WebEven at temperatures well below the boiling point of a liquid, some of the particles are moving fast enough to escape from the liquid. When this happens, the average kinetic energy of the liquid decreases. As a result, the liquid becomes cooler. It therefore absorbs energy from its surroundings until it returns to thermal equilibrium. WebIntroduction and aims: Extemporaneous preparations are those made by the pharmacist, usually by using previously prepared dosage forms such as tablets and creams. These preparations are prepared when there is a need to change the concentration or the dosage form of the drug.

WebThe vapor pressure of a liquid varies with its temperature, as the following graph shows for water.The line on the graph shows the boiling temperature for water. As the temperature of a liquid or solid increases its vapor pressure also increases.Conversely, vapor pressure decreases as the temperature decreases. WebThe viscosity of liquids decreases rapidly with an increase in temperature, and the viscosity of gases increases with an increase in temperature. Thus, upon heating, liquids flow more easily, whereas gases flow more sluggishly. For example, the viscosities of water at 27 °C (81 °F) and at 77 °C (171 °F) are 0.85 × 10 −3 and 0.36 × 10 ...
