Illustrating Signs of Chemical Change - Storyboard That A change in temperature, either an increase or decrease, can indicate a chemical reaction has occurred. When energy is released, the reaction can be described as exothermic. When energy is taken in, the reaction can be described as endothermic. Precipitation Sometimes when two liquids are combined, a solid can form.
