This week we have been learning exothermic and endothermic .One experience we did this week that helped me understand exothermic and endothermic, was your ice cream lab. In this lab, we used plastic bags, measuring cups, rock salt, and snow. The snow and the salt react to each other and the snow turns to ice. How this happens is when you shake the ice and snow it makes the snow melt then freeze over because of all the coldness from the snow. That would be considered an exothermic reaction, but if you didn’t have enough salt the reaction will be slower and it may not turn the snow into an exothermic reaction. That reaction will also is a endothermic reaction, because after it gets so cold it turns into ice and makes the surrounding cold as well. That is why we wore gloves to protect use from the cold exothermic and endothermic reaction that happens.
These reactions really are in everyday life and everything that is cold and warm. Like when we use hand warmer or frighes. The freight keep the cold which would mean that the freight is endothermic . The hand warmer is placing warmth into your hand and that is exothermic.what was satisfying about the lab was how it made so much sense and gave me an understanding of the exothermic and endothermic and it was really yummy! This was one of my favorite tests and the most interesting one for me. Now I really understand exothermic and endothermic.
If you have a fever and you feel chilly, but really you have a fever would that be exothermic or endothermic?
When you put heat into your house where is the cold going?
