Melting point vs freezing point
WebWe examined how first year students (10th grade) of Greek Senior High School could conceptualize the influence of the molecular weight of saturated fatty acids on the melting and the freezing point, during the "change of phase" phenomenon using the Microcomputer-Based Laboratory (MBL) system. Students had to freeze a melted … Web14. If you decrease the pressure, the freezing point of water will increase ever so slightly. From 0° C at 1 atm pressure it will increase up to 0.01° C at 0.006 atm. This is the triple point of water. At pressures below this, water will never be liquid. It will change directly between solid and gas phase (sublimation).
