Apr 07, 2022 A rotary evaporator is essentially a reduced pressure distillation: a solution in a round bottomed flask is placed in the water bath of the apparatus (Figure 5.66a), and rotated while the system is partially evacuated (by a water aspirator or vacuum pump). The reduced pressure in the apparatus causes the solvent to boil at a lower temperature ...

Dec 20, 2019 A rotary evaporator is electronically controlled so that the rotation of the flask can be kept at a constant speed, and the mixture can form a film on the inner surface of the flask, creating a larger surface for heating. All of these factors contribute to the faster evaporation speed of solvent, which means higher efficiency and better accuracy.

Evaporation- Inorganic Chemistry for Industries. Evaporation, in a technical sense, denotes the conversion of a liquid into a vapor for the purpose of separating it from another liquid of higher boiling point, or from a solid which is dissolved in it. In the great majority of cases, the liquid evaporated is water.

Jun 06, 2019 Mechanical work is the type of work most commonly dealt with in physics and chemistry. It includes work moving against gravity (e.g., up an elevator) or any opposing force. Work is equal to the force times the distance the object moves: w = F*d. where w is work, F is the opposing force, and d is the distance.

What is the Definition of Evaporation in Chemistry?

Technically, evaporation is defined as the ‘phase transition’ of a liquid into a gas when the liquid is still below its boiling point. As long as the substance is not completely frozen at absolute zero Kelvin temperature (minus 273.15C), evaporation can occur even below the normal room temperature. On the other hand, the boiling point of ...
