The first blank is hypertonic and the second blank is hypotonic
I'm pretty sure it is refraction <span />
Explanation:
To dissolve, solvent particles must come in contact with solvent particles. Particles of hot water are moving much more rapidly than particles of cold water. Hence, in hot water more water particles will come in contact with hot chocolate powder than in cold water, resulting in faster dissolving.
The change of temperature lava cools down/seconds it flows down.
polarity of a molecule deals with the presence of net charges and partial charges. this has nothing to do with its symmetry which is determined by the molecule's structure
