Water (2)

Question 1

Why is water a polar molecule?

Answer 1

oxygen is more electronegative than hydrogen, so attracts the electron density in the covalent bond more strongly

Question 2

How is water having a large latent heat of vaporisation important for organisms?

Answer 2

provides cooling effect

Question 3

What are 5 properties of water?

Answer 3

1) metabolite
2) solvent
3) high specific heat capacity
4) large latent heat of vaporisation
5) cohesion

Question 4

How is water being a metabolite important for organisms?

Answer 4

metabolite in condensation + hydrolysis reactions

Question 5

How is water being a solvent important for organisms?

Answer 5

allows metabolic reactions to occur

Question 6

How is water having a high specific heat capacity important for organisms?

Answer 6

can buffer changes in temperature

Question 7

How is water having cohesion important for organisms?

Answer 7

provides surface tension and supports columns of water
