premelting meaning in Hindi

Examples

1. The surface freezing effect is opposite to a far more common surface melting, or premelting.
2. Under premelting conditions, ice and water can coexist at temperatures below-10 �C in a porous medium.
3. For solid-solid interfaces it cannot be predicted in general whether the premelting is complete or incomplete when only considering van der Waals interactions.
4. A well-known example of this is the RBS analysis of the premelting of lead surfaces by Frenken, Maree and van der Veen.
5. Premelting shows its effects in e . g . frost heave, the growth of snowflakes and, taking grain boundary interfaces into account, maybe even in the movement of glaciers.
6. The term premelting is used to describe the reduction in the melting temperature ( below 0 �C ) which results from the surface curvature of porous media confining water ( the Gibbs-Thomson effect ).
7. The term premelting is used to describe the reduction in the melting temperature ( below 0 �C ) which results from the surface curvature of water that's confined in a porous medium ( the Gibbs-Thomson effect ).
8. A key phenomenon for understanding ice segregation in soil or porous rock ( also referred to as an ice lens due to its shape ) is premelting, which is the development of a liquid film on surfaces and interfaces at temperatures significantly below their bulk melting temperature.
