Antarctic ice loss expected to affect future climate change

In a new climate modeling study that looked at the impacts of accelerated ice melt from the Antarctic Ice Sheet (AIS) on future climate, a team of climate scientists reports that future ice-sheet melt is expected to have ...

Q&A: Treading on shrinking ice

Geophysicist Marco Tedesco has an affinity for ice in all its forms–snow, glaciers, ice sheets, sea ice–and has spent his career exploring its qualities and fates. He has worked in Antarctica and the United States, but ...

Chemists offer a new look at polymers for space industry

Employees of the Department of Physical Chemistry of Kazan Federal University have found that the mechanisms of polymerization of aryl cyanates in the solid state and in the melted state differ in the number of broken multiple ...

Melting

Melting, or fusion, is a physical process that results in the phase change of a substance from a solid to a liquid. The internal energy of a substance is increased, typically by the application of heat or pressure, resulting in a rise of its temperature to the melting point, at which the rigid ordering of molecular entities in the solid breaks down to a less-ordered state and the solid liquefies. An object that has melted completely is molten. Substances in the molten state generally have reduced viscosity with elevated temperature; an exception to this maxim is the element sulfur, whose viscosity increases with higher temperatures in its molten state.

Some organic compounds melt through mesophases, states of partial order between solid and liquid.
