... (Shc) of a substance is the amount of heat needed to raise the temperature of one kilogram of it by one degree Celsius. The specific heat capacity of water is 4.2kj Copper sulphate solution is mostly water, therefore its' Shc is about 4.2kj. We need to know this so we can calculate the heat energy produced in the reaction. The formula for heat energy produced is: Heat energy = mass x Shc x change in temperature As copper sulphate solution is mostly water it has a density of 1g/cm3, this means that the mass in grams has the same value as the volume in cm3. I.E. If the copper sulphate solution has a volume of 50cm3 it has a mass of 50g. This is because, density = mass Volume. In using the previously stated equations it should be quite easy to calculate the heat energy produced. Secondary Sources - Exercise ...
