- hmmm... Iwonder whatanexothermic reaction is? and a endothermic reaction?
- since we have been learning about this in school.

- HI scientist mike i am here to ask you questions about exothermic and endothermic reactions.
- Hi I am scientist mike what may I help you with today.
- since my mom singed me up for this class.

- An endothermic reaction is energy absosorbed from heat by the surroundings in the from of heat .
- So what is an endothermic reaction?
- שקופית: 4
- oh and an example of a endothermic reaction (with thermal energy) is eggs being cooked on the stove having to absorbed the heat.
- Thanks, mike.
- So what is an exothermic reaction?
- your welcome.

- So, an exothermic reaction is energy being released from heat.
- The example?
- The example of a exothermic reaction is being supplied with (thermal energy) is a campfire because the people sitting ...
- Oh thank you so much buy talking to you i understand so much more
- air around the campfire is getting warm as a result of released energy

- Before i go an example of an catalyst for a exothermic reaction is the freezing of ice ...
- So if the ice stays in the sun it will melt, and that will be a exothermic reaction?
- because if the ice loses its coldness it can mealt into water.
- Yes! I will say yes because exothermic releases from heat.
