WATER

Question 1

What is water?

Answer 1

A liquid constantly moving-this makes h2 bonds, MAKING DIFFICULT TO BECOME GAS.
Providing habitats for living things
Reaction medium
Effective transport medium.

Question 2

Water density

Answer 2

More dense when it becomes colder
as they align themselves to make them less dense.
ALLOWS-ice to float.
Aquatic organisms having stable environment too live in water.
Ponds-insulate against extreme conditions.

Question 3

Water-solvent

Answer 3

Water is polar.
+ and - attracted- so water molecules attracted, by clustering around.

Question 4

Water-specific high capacity

Answer 4

Water-doesn’t heat up/cool easily, so stable for enzyme controlled reactions.
Aqautic need stable environment to stay in .

Question 5

High latent heat of vaporisation

Answer 5

Due to held by h2 bonds, large amounts of energy needed to evaporate, which helps cool living things, to keep temp stable.
