... I will be able to change different parts of the experiment. These are: * Volume of water heated: Depending on how much water we use depends on how long it takes to heat up. If we heat a large volume of water it will take it longer to heat up, as there will be more molecules for the heat from the spirit burner to give energy to, it will take longer for the water molecules to get enough energy to loosen and break, so the reaction will be slower. If we only use a small volume of water the heat energy from the spirit burner will give the water molecules energy faster as there are will less of them so more heat energy per molecule, this means the bonds will loosen and break quicker so the reaction will be faster. * Distance between spirit burner and Copper Calorimeter: The further the ...
