Biological role of water

Bonding between atoms inside water molecule

• hydrogen

• ionic

• covalent polar

• covalent nonpolar

Bonding between water molecules

• covalent polar

• covalent nonpolar

• ionic

• hydrogen

Sticking water molecules to surfaces is called

• adhesion

• cohesion

• polarity

• solubility

Interaction between two water molecules is called

• adhesion

• cohesion

• ionic bonding

• polarisation

Ability to accumulate heat is called

• specific heat capacity

• latent heat of vaporisation

• latent heat of fusion

• boiling point

Water is good coolant, because:

• it changes temperature with difficulties

• evaporating water takes heat from the skin

• boiling point for water is very high

• water evaporates below it's boiling point

A substance that dissolves in water is called:

• hydrophilic

• hydrophobic

• polar

• insoluble

A substance that does not interact with water is called:

• hydrophilic

• hydrophobic

• nonpolar

• polarised

Ability of water to evaporate below it's boiling point is called:

• specific heat capacity

• latent heat of fusion

• latent heat of vaporisation

• cohesion
