AExothermic
BEndothermic
CIsothermal
DAdiabatic
Answer & Solution
Correct answer: A. Exothermic
1. The prefix records the direction heat travels.
2. A change that releases heat is called an exothermic process.
3. A change that absorbs heat runs the other way and is endothermic.
4. Isothermal describes constant temperature rather than heat direction.
