Strategy:
 Endothermic processes () are those that absorb heat from the surroundings. This typically includes bond breaking and phase transitions toward higher energy states (like liquid to gas).

Step 1: Classify each process
- A. : Breaking the  bond requires energy input  Endothermic.
- B. : Breaking the  bond requires energy  Endothermic.
- C. : Vaporization requires heat to overcome intermolecular forces  Endothermic.
- D. : Combustion is a heat-releasing process  Exothermic.
- E. Dissoluti
