To compare the mass of ammonium chloride to its temperature change when water is added to it. Aim: To see the temperature change when different amounts of ammonium chloride are added to water. Resources: Before doing the experiment I looked at the book "The Material world" and "GCSE revision guide" and have found information on endothermic reactions. I have highlighted the relevant information in my scientific knowledge. This information will help me make a prediction. Scientific Knowledge: There are two types of reactions, exothermic and endothermic reactions. I will be concentrating on endothermic reactions as the reaction I am to plan is going to be endothermic. An endothermic reaction is when energy is gained, and therefore the temperature of the reaction decreases when the two substances are mixed. So when a solid dissolves, energy is used to break up the giant lattice. The energy used is greater than the energy released by...
