- well Lisa this is and endothermic because the water is getting hotter that means it is being supplied and a endothermic reaction is when something absorbs heat or another word adds heat.
- Ava is this a endothermic or a exothermic .
- well I heard you guys talking and I wanted to give some everyday examples of exothermic and endothermic.
- Well a exothermic reaction is when energy is being released, like a campfire it is giving us heat.
- So what is a exothermic.
- The teacher narrating .what if Ava were to light a scented candle to give off a good vibe at night the candle would be releasing heat to the room. That is an example of exothermic.
- And a example of endothermic is when you you are wearing a coat you absorb heat
- what if we add more coal to this what would be.
- That would be a catalyst because it speeds up the reaction.
- Just a reminder Thermal energy are different because thermal energy between molecules
