Question
1. Define the following terms, in your own words, as they relate to this experiment a. volatile b. evaporation c. condensation 2. Why should this experiment be carried out in a well-ventilated area? 3. There is a pin-hole in the top of the aluminum foil cap though which some of your sample could potentially escape Considering the density of the unknowns at 100 °C is greater than that of air, do you need to be concerned with losing a lot of your sample through this hole? What will be forced out? 4. How will you know the vaporization process is complete?Explanation / Answer
1ans:-
(a) VOLATILE:- Substances which are easily evaporate even at room temperature are known as volatile Substances. for e.g :- petrol , diesal etc. are the volatile liquids .
Note:- Water is also a volatile but it's volatility is very very less than petrol or diesel.
(b) EVAPORATION:- evaporation is a surface phenomenon in which liquids converted into gaseous phase. Evaporation increases with increase in temperature.
Note:- evaporation of water at room temperature is a spontaneous process.
CONDENSATION:- Condensation is opposite process of evaporation i.e in condensation vapours converted into liquid phase , but this is possible only in close container.
Note:- at equilibrium state rate of condensation in a close container is equal to rate of evaporation.
