supercooling उदाहरण वाक्य
उदाहरण वाक्य
- Superheating, supercooling, or supersaturation can happen when the water molecules are very still, and very pure, without other molecules around them.
- When a dendrite growth cycle was completed, the small crystalline structure was re-melted and another grown at a different " supercooling " temperature.
- We can say then that the size of the initial and transition zones are controlled by the extent of supercooling beyond the already low freezing temperature.
- When solidifying a liquid, the interface is often unstable, and the velocity of the solid liquid interface must be small in order to avoid constitutional supercooling.
- Unlike the transition to gas, there is no equilibrium at this transition under constant pressure, so unless supercooling occurs, the liquid will eventually completely crystallize.
- If the freeze-casting setup is controlled so that nucleation is favored at only small supercooling, then the TZ will give way to the SSZ sooner.
- For instance, MgSO 4 has a eutectic of-3.6�C but through supercooling can remain liquid for an extra-15.5�C below that.
- If the material is kept still there is often nothing ( such a physical vibration ) to trigger this change, and supercooling ( or superheating ) may occur.
- The fluids eventually reach the supercooling point, which is the temperature at which the supercooled solution freezes spontaneously due to being so far below its normal freezing point.
- Constitutional supercooling, which occurs during solidification, is due to compositional changes, and results in cooling a liquid below the freezing point ahead of the solid liquid interface.
