A. Fish and other animals can survive through the winter even if the water molecules stick to the glass as well as the molecules in the air creating a dip in the water and keeping it in form in the graduated cylinder or other glass object. ​

B. Water is adhesive and forms with other hydrogen bonds with polar surfaces. Because the substances are polar the negatively charged O2 regions of water cling to the positively charged cations surrounding them and the positively charged hydrogen regions are attracted to and surround the chloride anions. This separates the sodium and chloride ions dispersing them evenly among the water. ​
