![]() | Elementary Productions: Endothermic reaction In this experiment, two solid (Ammonium Nitrate and Barium Hydroxide) are added to a beaker. As they react, Ammonia gas, water and Barium Nitrate are produced. This results in a large increase in entropy, which is the measure of randomness in a system. This again causes the temperature to drop, as there is an increase in Enthalpy |

![]() | Endothermic & Exothermic Electric Discharges Everyone knows that electricity can be used to generate heat. What most people don't know is that electricity can also be used to generate cold. These two reactions are called exothermic and endothermic. Exothermic means energy is radiated outward. Which usually generates heat or heating. Endothermic means energy is radiated inward which usually generates cold or cooling. Both effects have a distinct sound when done rapidly. Exothermic will have a loud snap or bang. This is because the reaction forces air and energy away from the point of discharge, making a temporary vacuum which is then quickly filled in by the surrounding air, creating a snapping sound. Endothermic however does not make a loud snap or bang. This is because the reaction absorbs energy around it. This makes a ping sound, like when you hit a piece of hollow medal with a vacuum inside. Endothermic discharges are also hard to capture on camera because some of the photons from the discharge are quickly absorbed into the vacuum.
