Icy reception for plan to 'save' Venezuela's last glacier
A small patch of ice among bare rock is all that remains of Venezuela's last glacier, which the government hopes to restore to its former glory using a geothermal blanket.

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.
