Answer:
It’s freezing point will be below 0°C due to the presence of a non-volatile
impurity in it.
12. Since ice and water are in equilibrium, the temperature would be zero.
When we heat the mixture, energy supplied is utilized in melting the ice
and the temperature does not change till all the ice melts because of latent
heat of fusion. On further heating, the temperature of the water would
increase. Therefore the correct option is (d).
13. (a) cooling
(b) stronger
(c) liquid, gaseous
(d) sublimation, liquid
(e) evaporation

16. Yes, this is true. In both the phenomena, there is movement of particles
from region of higher concentration to that of lower concentration. However,
in the case of osmosis the movement of solvent is through a semi permeable
membrane which is permeable only to water molecules.
