Question

match the terms review.

1. cohesion
2. capillary action
3. adhesion
4. polarity
5. hydrogen bond
6. surface tension
7. specific heat

a. tendency to stick to other substances
b. tightness caused by the pulling of water molecules on each other
c. the amount of heat needed to raise 1kg of a substance 10
d. weak bonds formed between water molecules
e. tendency to stick to other water molecules
f. uneven distribution of charges in a molecule
g. tendency to climb up due to cohesion and adhesion properties of water

Explanation:

1. Cohesion is the tendency of water molecules to stick to each other, so 1 - b.
2. Capillary action is the tendency to climb up due to cohesion and adhesion properties of water, so 2 - g.
3. Adhesion is the tendency to stick to other substances, so 3 - a.
4. Polarity refers to the uneven distribution of charges in a molecule, so 4 - f.
5. Hydrogen bond are weak bonds formed between water molecules, so 5 - d.
6. Surface tension is caused by the pulling of water molecules on each other, so 6 - e.
7. Specific heat is the amount of heat needed to raise 1kg of a substance 10, so 7 - c.

Answer:

1. b. tightness caused by the pulling of water molecules on each other

3. a. tendency to stick to other substances
4. f. uneven distribution of charges in a molecule
5. d. weak bonds formed between water molecules
6. e. tendency to stick to other water molecules
7. c. the amount of heat needed to raise 1kg of a substance 10
