A. Give reason for the following.
1. We sweat more in rainy season.
2. One cannot hear the sound of clapping on the moon.
3. Method of filtration cannot be used to separate sugar from the sugar solution.
Answers
1. On dry days, sweat evaporates quickly, which means it also carries away heat faster. On humid days, when the air is already saturated with water, sweat evaporates more slowly. This explains why it feels so much hotter in high humidity.
2.Well, No. You cannot hear any sound on moon. “Sound” is actually vibrations in the air or let's just say a medium. Sound can travel in the atmosphere of the moon, which is space, because the gases in it can propagate sound just like the air on earth transmits it, but we certainly cannot hear it.
3.Ans: Filtration is a method that is used to separate insoluble solids from a liquid. Since salt and sugar both dissolve in water, filtration cannot be used to separate the two.
