Q: Given a scientific passage and an answer, generate a question for the given answer.
Passage: The process in which rocks or other solids change to liquids is called melting. Melting occurs when particles of a solid absorb enough energy to partly overcome the force of attraction holding them together. This allows them to move out of their fixed positions and slip over one another. Melting, like other changes of state, is a physical change in matter, so it doesn't change the chemical makeup or chemical properties of matter. Answer: at temperatures above 0 degrees c
A:
At what temperature does solid water melt to a liquid?
