ngoại thẩm
Definition
- Noun (Physics/Chemistry):
- Exosmosis: The outward flow of a fluid (especially a solvent) through a semipermeable membrane, from an area of higher concentration to an area of lower concentration. It is the opposite process of endosmosis.
Usage Examples
- Noun:
- Hiện tượng ngoại thẩm xảy ra khi tế bào thực vật được đặt trong dung dịch ưu trương. (The phenomenon of exosmosis occurs when a plant cell is placed in a hypertonic solution.)
- Sự co nguyên sinh là kết quả của ngoại thẩm. (Plasmolysis is the result of exosmosis.)
Advanced Usage
- This is a specialized scientific term. Its usage is almost exclusively confined to academic contexts in biology, chemistry, and physics when describing the movement of solvents across cell membranes or artificial membranes.
Variants and Related Words
- Thẩm thấu (n): Osmosis - the general process of solvent movement across a membrane.
- Nội thẩm (n): Endosmosis - the inward flow of a solvent through a semipermeable membrane.
Synonyms
- Exosmosis (direct equivalent)
Related Scientific Concepts
- Osmosis: The net movement of solvent molecules through a semipermeable membrane into a region of higher solute concentration.
- Plasmolysis: The process in plant cells where the cytoplasm shrinks away from the cell wall due to exosmosis.
- Hypertonic Solution: A solution with a higher solute concentration than the cell, causing exosmosis.
