What is water?
1)Liquid at RTP.2)Molecules join by hydrogen bonds.3)Hydrogen and Oxygen joined by covalent bonds.4)Universal solvent.5)High surface tension, can be used as a habitat.
1 of 8
Is water polar?
Yes, hydrogen is slightly positive and oxygen is slightly negative.
2 of 8
Water is a solvent, how is this significant?
Allows transportation.
3 of 8
Water has high surface tension, how is this significant?
1)It's a habitat to some animals and insects, live on surface.2)Water used in plants to transport water from roots to leaves.
4 of 8
Water has specific heat capacity, how is this significant?
1)Hard to increase temperature of water, so enzymes won't denature.2)Organisms in waters enzymes won't denature.3)Sweat acts as cooling mechanism.
5 of 8
Waters density decreases the colder it gets, how is this significant?
1)Ice acts as insulator to water underneath.2)Ice floats-habitat for animals.
6 of 8
Water is a metabolite, how is this significant?
1)Hydrolysis and photosynthesis-where water is a reactant.
7 of 8
Water is transparent, how is this significant?
1)Plants under water can photosynthesise, producing oxygen.
