Ever wonder how you can tell if a chemical reaction is hot or cold just by looking? This video breaks down the clear, observable signs that reveal whether a reaction is endothermic or exothermic. Discover the key indicators that distinguish between these fundamental reaction types: ► Learn to identify exothermic reactions through noticeable heat release and temperature increases. ► Understand how endothermic reactions manifest as a decrease in temperature, feeling cold to the touch. ► Explore visual cues like light emission or gas production that often accompany these energy changes. ► Gain insight into the energy transfer occurring during chemical processes. #ChemistryReactions, #Endothermic, #Exothermic, #ScienceExperiments, #ChemistryBasics, #STEM
