Water

Question 1

What is the property of High Latent Heat of Vapourisation of water

Answer 1

Lots if energy required to break Hydrogen bonds, so lots of energy required to evaporate water.

When water evaporates, thermal energy is released away from the surface, hence it can cool body temperature.

Question 2

What is Cohesion in terms of water

Answer 2

Hydrogen bonds cause surface tension when water meets air because H2O molecules pack together.

Cohesion allows water to move up the stems of plants.

Question 3

How is water a Good Metabolite

Answer 3

Used or formed in many metabolic reactions.

Involved in hydrolysis and condensation reactions.

Question 4

How is water a Solvent

Answer 4

Substances which are charged, or polar themselves, dissolve in water.

Solvent in which metabolic reactions occur.

Question 5

How does water have a High Heat Capacity?

Answer 5

Due to numerous Hydrogen bonds.

Takes a LOT of energy to change temperature.

So water can buffer any change of temperature in a living organism.
