31. The liquid phase flows downward through the column via gravity, while the gas phase flows upward. 32. These properties are colligative in systems where the solute is essentially confined to the liquid phase . 33. He did this by calculating Avogadro's number using three different methods, all involving liquid phase systems. 34. For materials which are difficult to sinter, a process called liquid phase sintering is commonly used. 35. And L here refers to the liquid phase . 36. For this reaction to occur in liquid phase mostly the catalyst magnesium aluminium double oxide is used. 37. This is usually a solid to liquid phase due to the small volume difference between these states. 38. But the permeate is in liquid phase . 39. The liquid phase refers to soil water. 40. Inside the column there are instead always two phases : one gas phase and one liquid phase .
