Final answer:
Option a)Boiling water is the endothermic process among the provided options, as it absorbs heat to transition from a liquid to a gas.
Step-by-step explanation:
An endothermic process is one that absorbs heat from its surroundings, while an exothermic process releases heat. Among the options provided:
- A) Boiling water: Endothermic - Water absorbs heat to transition from a liquid to a gas.
- B) Freezing point of water: Exothermic - Water releases heat as it transitions from a liquid to a solid state.
- C) Condensation of steam: Exothermic - Steam releases heat as it transitions from a gas to a liquid.
- D) Combustion of wood: Exothermic - Wood releases heat as it burns.
Therefore, the endothermic process among the given options is A) Boiling water.
