Boiling melting and freezing point of water
WebChemistry questions and answers. Part 2: Liquid and Gas water model 1) Investigate what is the melting/freezing point AND the boiling/condensation point of water in Kelvin. Record this information in your TABLE 2. 2) Add heat until the temperature is just below the melting point of water and then just above the melting point of water. WebJan 28, 2024 · Changes in pressure can raise or lower the freezing point of a substance. Generally, pressures lower than 1 atmosphere lower the temperature at which a substance freezes, but for water, a higher pressure gives a lower freezing point. For water at low pressures, vapor directly turns to ice without becoming a liquid.
