Properties of water

Question 1

Adhesion

Answer 1

Occurs because of the polarity of water molecules and its ability to form hydrogen bonds.

Question 2

Capillary

Answer 2

It is caused by the combination of adhesive and cohesive forces.

Question 3

Cohesion

Answer 3

Surface Tension is caused by the Cohesive hydrogen bonding resting on an object trying to penetrate the surface of liquid water

Question 4

High specific Heat Capacity

Answer 4

Hydrogen bonds restrict the motion of the water and require a large input of energy to break.

Question 5

High Latent Heat Of Vaporisation

Answer 5

In order for matter to change state from a liquid to a gas, heat is required.
The evaporation has a cooling effect as a considerable amount of heat is used to break the hydrogen bonds.

Question 6

Solvent

Answer 6

dissolves Polar/ unpolar molecules

Question 7

Amphipathic

Answer 7

Molecules that are both Hydrophilic (water loving ) and Hydrophobic(water hating) .

Question 8

Adhesive Force

Answer 8

refers to the attractive forces between unlike substance

Question 9

Chromatography and adhesive force

Answer 9

the interaction between adhesive and cohesive forces
