Water

Question 1

What is a metabolic reaction

Answer 1

A condensation or hydrolysis reaction that happens in a living organism to keep the organism alive

Question 2

What is a metabolite

Answer 2

A substance involved with a metabolic reaction

Question 3

What does solvent mean

Answer 3

Substances dissolve into it

Question 4

What properties does water have

Answer 4

• metabolite
• solvent
• high latent heat of vaporisation
• high specific heat capacity
• cohesive

Question 5

What does cohesive mean

Answer 5

When molecules stick together

Question 6

What is a hydrogen bond

Answer 6

A bond between a hydrogen atom and a different molecule such as another oxygen atom in a water molecule

Question 7

What does a high latent heat of vaporisation mean

Answer 7

It takes alot of energy (heat) to break the hydrogen bonds which makes it so that living organisms can lose water loss through evaporation to cool down (sweating)

Question 8

What does high specific heat capacity mean

Answer 8

The hydrogen bonds can absorb a lot of energy, takes a lot of energy to heat water up, makes water a good habitat because stable temperature

Question 9

What does polar mean

Answer 9

One end of the molecule is positive and one end is negative

Question 10

What does high surface tension mean

Answer 10

Significant resistance to penetration compared to the rest of the liquid allowing pond skaters to ‘walk’ on the surface of a pond
