endothermic exothermic reactions, scientific method Flashcards
What is an exothermic reaction?
A reaction where energy is released, often in the form of heat and light.
How do the energy levels of products compare to reactants in exothermic reactions?
Products have less energy compared to reactants; this is why they are known as downhill reactions.
What is an endothermic reaction?
A reaction where energy is absorbed, like in ice packs where chemicals mix and absorb heat.
How do the energy levels of products compare to reactants in endothermic reactions?
Reactants have less energy, and products have more energy; this is why they are known as uphill reactions.
What is the scientific method?
A process of testing an idea to determine if it is true.
: What are the steps of the scientific method?
A: 1. Observation
2. Forming a question
3. Create a hypothesis
4. Investigation
5. Analyzing data
6. Reaching a conclusion
