Answer 2

hydrogen bond

Question 3

water can dissolve more substances than any other liquid

Answer 3

universal solvent

Question 4

water molecules are very attracted to each other as they “stick” together. Due to hydrogen bonds and polarity of water

Answer 4

cohesion

Question 5

water molecules can stick to other elements; water sticks to paper towels

Answer 5

adhesion

Question 6

combination of cohesion and adhesion that moves water up thin tubes and paper towels

Answer 6

capillary action

Question 7

Answer 7

evaporative cooling

Question 8

water is less dense as a solid than as a liquid. this allows ice to float and insulate water beneath it so it does not freeze
