Question
-The heat needed to vaporize a liquid depends on (it's heat capacity or amount).
-Which of the following statements is correct? a) Unsaturated solutions are relatively unstable. Supersaturated solutions are relatively unstable. c) A solution becomes saturated when the solute dissociates completely to ions. d) All of these statements are correct. e) None of these statements are correct.
-Cubic closest packing coordination number? & number of atoms.
-the equilibrium vapor pressure of a liquid depends on it's temperature or external pressure.
Explanation / Answer
The heat needed to vaporize a liquid depends on its heat capacity .beacuse it is intensive property which means per gram of liquid how much heat is required.
(b)
The correct answer is Supersaturated solutions are relatively unstable. This is because this is very hard to prpare ans they need some mechanical agents like temperature and pressure
(c) Cubic closest packing coordination number 12 & number of atoms 4
(d) the equilibrium vapor pressure of a liquid depends on it's temperature .Since K depends on temperature
