Step 1I'll solve this problem by explaining the energy changes during phase transitions with a focus on vaporization and condensation.
Step 2: Understanding Phase Transitions
Phase transitions involve changes in the energy state of molecules as they move between different states of matter. In the case of vaporization and condensation, we're focusing on the transition between liquid and gas states.
Final Answer
- Vaporization is endothermic because energy is absorbed to break intermolecular bonds - Condensation is exothermic because energy is released when intermolecular bonds reform
