100-year-old physics model replicates modern Arctic ice melt

The Arctic is melting faster than we thought it would. In fact, Arctic ice extent is at a record low. When that happens—when a natural system behaves differently than scientists expect—it's time to take another look at ...

Video: Visualizing the global thaw

One of the causalities of climate change is the diminishing ice cover, affecting our planet in a number of ways.

Getting fertilizer in the right place at the right rate

We've all heard about the magical combination of being in the right place at the right time. Well for fertilizer, it's more accurate to say it should be in the right place at the right rate. A group of Canadian scientists ...

Warm winds in autumn could strain Antarctica's Larsen C ice shelf

The Antarctic Peninsula is the northernmost part of Earth's coldest continent, making it particularly vulnerable to a changing global climate. Surface melting of snow and ice initiated the breakup of the peninsula's northernmost ...

Melting glaciers causing sea levels to rise at ever greater rates

Melting ice sheets in Greenland and the Antarctic as well as ice melt from glaciers all over the world are causing sea levels to rise. Glaciers alone have lost more than 9 trillion tons of ice since 1961, raising water levels ...

New 3-D printing approach makes cell-scale lattice structures

A new way of making scaffolding for biological cultures could make it possible to grow cells that are highly uniform in shape and size, and potentially with certain functions. The new approach uses an extremely fine-scale ...

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.
