Rate of Evaporation of Different Liquids Objective of the Project This project is of the rate of evaporation of different liquid‚ in which we also discuss the factors which affect the rate of liquid. Introduction When liquid is placed in an open vessel. It slowly escapes into gaseous phase ventually leaving the vessel empty. This phenomenon is known as vaporization or evaporation. Evaporation of liquids can be explained in the terms of kinetic molecular model although there

Evaporation is one of the main methods used in chemical industry for concentration of aqueous solutions that means the removal of water from solution by boiling the liquor in a suitable type of evaporator and withdrawing the vapor (Coulson & Richardson‚1983). The objective of evaporation is to concentrate a solution consisting of non-volatile solute and a volatile solvent. In the overwhelming majority of evaporations the solvent is water. Normally‚ in evaporation the thick liquor is the valuable

An experiment to find the percentage of three separated components Research Question: Is it possible to separate salt‚ sand and iron filings from each other in a mixture‚ to figure out the percentage of each component in the original mixture? Background Research: In this Investigation‚ I will be separating sand‚ salt‚ iron fillings in a mixture and finding their percentages. Iron is a magnetic solid which is incapable of being dissolved in water. Salt is a non-magnetic solid which is capable

Evaporation and Transpiration Evaporation and transpiration (evapotranspiration) are components of hydrologic cycle‚ which at principle‚ can be calculated from meteorological observations such as temperature‚ humidity‚ radiation‚ wind speed‚ etc. The process‚ however‚ is quite complex and a substantial literature has been produced on it. In this chapter our focus is mainly on the concept and simple estimations of evaporation and transpiration. Mechanism of evaporation from water surfaces Here

Internal Assessment: Rate of Evaporation Ann George Mr. Frias/4th Period Wheeler High School Research Question How will changing the molar mass of alcohol affect the rate of evaporation‚ represented by the change in temperature over time‚ measured using a temperature probe? Research/Abstract Alcohol is an organic compound in which the hydroxyl functional group‚ OH‚ is bound to a carbon atom. Its carbon center should be saturated; it should have single bonds to three other atoms. The different types

Technique of Water Evaporation Introduction When water evaporates from water storages it becomes a major issue that affects regions of agriculture in most lands leading to annual loss exceeding potentially to 40 precent and more of water storage. This water which is lost leads to reduction of productivity in agriculture affecting the environment adversely. Literature review has been developed on the same by various researchers in order to develop evaporation suppression techniques

Vapor Pressure and Heat of Vaporization Introduction: Evaporation is the process of a liquid becoming vaporized. When a liquid is placed into a confined space some of the liquids will evaporate. Evaporation of the liquid depends on the strength of the intermolecular forces that are between liquid molecules. During the evaporation process of the liquid‚ new gas molecules exerts pressure in the sealed container‚ while some of the gas condenses back to the liquid state. If the temperature inside

the Rate of Evaporation? Aim * To find out if changes in temperature‚ draught and surface area of water open to air affects the rate of evaporation through the water. * To safely check if these variables change the rate of evaporation * To complete all the experiments in the short period given Prediction * I believe that a raise in temperature will speed up the rate of evaporation in the water * I believe that a larger surface area will speed up the rate of evaporation in the water

(1) Evaporation: Surface Area: Evaporation is surface phenomenon.Greater is surface area greater is evaporation and vice versa.For example‚ sometimes a saucer is used if tea is to be cooled‚ quickly.This is because evaporation from the larger surface area of saucer is more than that of the smaller surface area of the tea cup. Temperature: At high temperature‚ rate of evaporation is high because at high temperature
