osmotic pressure

nounɒzˈmɒtɪkäzˌmätik ˈpreSHər

    〔化〕渗透压力

    Example sentencesExamples
    • If a U-shaped glass tube were divided in two by a semipermeable membrane and filled with two solutions the osmotic pressure could be shown.
    • However, it seems that organic acids account for less than half of the osmotic pressure induced by osmotically active compounds other than sugars.
    • The driving force for the osmotic pressure is the higher concentration of sodium ions in the beads than in the outside water.
    • The glucose osmotic pressure in solution with water is proportional to the glucose concentration in the outer solution.
    • The solution also creates a strong osmotic pressure on the cell walls of bacteria and other micro-organisms, which prevents them from passing substances in or out.
