Melting point of water - Answers
2024年6月8日 · The melting point of water is 0 degrees Celsius (32 degrees Fahrenheit). At this temperature, solid ice changes to liquid water as thermal energy breaks the bonds holding the water molecules together.
What is the melting point of water at 5000 of altitude? - Answers
2024年1月4日 · The melting point of water at 5000 meters is slightly higher than at sea level due to the lower atmospheric pressure. At this altitude, water will freeze at around 0.2 degrees Celsius.
