Water 0.0 / 5 ? BiologyBiological moleculesASOCR Created by: JemmaVenessCreated on: 27-04-16 17:43 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 11 of 11
