Start of an endothermic reaction. Solid barium hydroxide and solid ammonium chloride have been place in a flask that is sitting on a damp piece of wood. The digital thermometer shows the temperature in the flask to be 21 degrees Celsius. As the two chemicals mix an endothermic,or heat-absorbing,reaction will take place and the temperature inside the beaker will drop dramatically. This drop in temperature will freeze the water between the flask and wooden block,sticking the two together | |
