The snow on the mountains does NOT melt all at once when it is heated by the sun because:
Correct answer: D. it has a high latent heat of fusion
- A. it becomes very hard
- B. it reflects most of the heat from the sun
- C. it has a low specific heat capacity
- D. it has a high latent heat of fusion
Explanation
Ice requires a large amount of latent heat of fusion to change into water without a temperature rise. Therefore, even under sunlight, mountain snow melts gradually rather than all at once.
