Water

HideShow resource information
What is the function of water?
Vital to living organisms, transports substances, helps with temperature control
1 of 11
Describe water
A reactant in lots of reactions e.g hydrolysis reactions, a solvent, high specific heat capacity, hight latent heat of evaporation, a habitat
2 of 11
Describe the structure of water
1 x oxygen, 2 x hydrogen joined by shared electrons.
3 of 11
What is a polar molecule?
A partial negative charge on one side and a partial positive charge on the other side.
4 of 11
What is hydrogen bonding?
When a slightly negatively charged oxygen atom attracts the slightly positively charged hydrogen atoms of other water molecules
5 of 11
What is specific heat capacity?
This is the energy needed to raise the temperature of 1g by a substance by 1*c
6 of 11
Why is this useful?
Water doesn't experience rapid temperature changes which makes it a good habitat because of this
7 of 11
Why is the high latent heat useful?
Good for cooling things
8 of 11
What is cohesion and why is it useful?
Attraction between molecules of the same type
9 of 11
Water's polarity makes it a good solvent
The polarity means that they will dissolve, which is good for humans
10 of 11
Water's less dense when its solid
Ice floats-useful in humans etc, fish don't freeze under the ice so they don't die
