Water And Its Properties

Question 1

What are the key properties of water

Answer 1

-it is a metabolite
-it is a solvent
-high specific heat capacity
-latent heat of vaporisation

Question 2

What is meant by water being a solvent in reactions

Answer 2

-Water can act as a solvent in reactions and can allow certain molecules to dissolved into it

Question 3

What is specific heat capacity

Answer 3

-The amount of energy needed to raise the temperature of 1 kg of a substance by one degree

Question 4

Specific heat capacity water, why is it high, and what is waters?

Answer 4

-Water has a high specific heat capacity, which is 4200j/kg which means water works well as a buffered temperature
-this helps to prevent the denaturation of enzymes

Question 5

Why does water have a high latent heat of vaporisation

Answer 5

Hydrogen bonds between water molecules mean that it requires lots of energy to evaporate 1 kg of water

Question 6

What is cohesion

Answer 6

Tendency of water to stick together

Question 7

What is surface tension

Answer 7

Where water meets air it’s the tendency for water to be pulled back into the body of water
