Endothermic and Exothermic (Lab)
Journal
Find your pink unit intro sheet. Look at #19 and 20. Tell me if the following are endothermic or exothermic:
If you missed this lab, complete the lab questions below as your makeup assignment:
1. Research what causes the reaction in reusable hand warmers (explain):
2. How are these hand warmers “reusable”?
3. Research how adding salt to ice water will affect the temperature of the water. Is this an endothermic or exothermic process?
4. Research the reaction of adding baking soda to vinegar. Is this an endothermic or exothermic reaction? Draw an energy graph of this reaction. Would you expect the temperature of this reaction to increase or decrease?
