Answer 19

IONIC BONDS

Question 20

H-Bonding

Answer 20

IT IS A FRACTION BETWEEN TWO POLAR MOLECULES DUE TO THEIR OPPOSITELY CHARGED SEGMENTS

Question 21

polar molecules attract and bind to each other (______) by hydrogen bonding and are attracted to other molecules (_______)

Answer 21

COHESION and ADHESION

Question 22

it takes a lot of energy to break the hydrogen bonds between water molecules so water keeps its temperature fairly consistent

Answer 22

SPECIFIC HEAT

Question 23

Due to H-bonding, water molecules are held together, roll into a ball, or can keep things on their surface. This is due to high ________.

Answer 23

HIGH SURFACE TENSION

Question 24

water is able to dissolve a wide range of other substances

Answer 24

UNIVERSAL SOLVENT

Question 25

water is denser than ice, so ice floats on water

Answer 25

DENSITY

Question 26

Color of water

Answer 26

Water is a very stable molecule without free moving electrons that would cause color. As a result, water is colorless

Question 27

Water viscosity…

Answer 27

Water molecules are very small and easily roll off of each other, so they flow easily. So water has a low viscosity

Question 28

viscosity..

Answer 28

Viscosity is a measure of a fluid’s resistance to flow.
