Give an example where heating results in contraction?
If water at 0oC is heated, it will contract, instead of expanding. This contratction will continue till 4oC. After 4oC, water will behave as normal substance and start to expand.
How do you prove that the mass of a substance of a density is equal to the volume of water?
Submerse the object in a completely full bucket. measure the volume of the displaced water due to the object. Multiply the volume of the displaced water by the density of the object to give mass.

How much does 18.5 liters of water weigh?
You need the density of the substance. You will need do to some conversions in order to get it in terms of pounds per liter. After you have the density just multiply it by the volume to give you the mass.

How do you clean up strong acid spillages eg sulphuric acid?
Initially , water, which will dilute the acid. You can add powdered chalk , calcium carbonate'. This will neutralise the acid to its salt. e.g. H2SO4 + CaCO3(chalk) = CaSO4(salt) + H2O +CO2 Note all the acid has gone.
What solution would alkali and acid give if added together?
It would depend on which acid and alkali were involved, the general rule is that adding an acid to an alkali will produce a salt and water. Sulphuric acid and sodium hydroxide would give sodium sulphate + water Hydrochloric acid and potassium carbonate would give potassium chloride and water and carbon dioxide etc
Could you give me an example using the word solidify?
