Energy & Reactions
An exothermic reaction releases energy. We use exothermic reactions in burning fuels as a source of energy. However, some reactions give off more energy than others, so we can calculate how much energy is released in a given reaction. There is apparatus available to do this called a calorimeter. An accurate version is the bomb calorimeter.
A bomb calorimeter works by measuring the temperature of the water inside it – because the energy produced in an exothermic reaction increases the temperature of its surroundings…
