Question

the melting of ice is considered a/an ______ because the ice absorbs heat from the surroundings. a) exothermic process b) chemical reaction c) endothermic process d) thermochemical process

Explanation:

To solve this, we analyze each option:

• Option A: Exothermic processes release heat, but ice melting absorbs heat, so A is incorrect.
• Option B: Melting ice is a physical change (state change), not a chemical reaction, so B is incorrect.
• Option C: Endothermic processes absorb heat from the surroundings. Ice melting (solid to liquid) requires heat absorption, so this matches.
• Option D: Thermochemical processes involve heat in chemical reactions, but melting is physical, so D is incorrect.

Answer:

C. endothermic process
