Superheating can occur when an undisturbed container of water is heated in a microwave oven. At the time the container is removed, the lack of nucleation sites prevents boiling, leaving the surface calm. However, once the water is disturbed, some of it violently flashes to steam, potentially spraying boiling water out of the container. [6]
Water is a polar molecule, where the centers of positive and negative charge are separated; so molecules will align with an electric field. The extensive hydrogen bonded network in water tends to oppose this alignment, and the degree of alignment is measured by the relative permittivity. Water has a high relative permittivity of about 80 at ...
When pressed enough, its sensitivity is reduced or destroyed; this is known as dead pressing. It also decomposes in boiling water. In contact with fire, it readily explodes, producing large amounts of black smoke. It is prepared by reacting sodium nitrite with an aminoguanidine salt dissolved in acetic acid at 30–40 °C.

Water temperatures of 238 °C at 332 meters have been recorded at Norris Geyser Basin. [5] Pocket Basin was originally an ice-dammed lake over a hydrothermal system. Melting ice during the last glacial period caused the lake to rapidly drain, causing a sudden change in pressure triggering a massive hydrothermal explosion.
Littoral explosion at Waikupanaha ocean entry at the big island of Hawaii was caused by the lava entering the ocean. A steam explosion is an explosion caused by violent boiling or flashing of water or ice into steam, occurring when water or ice is either superheated, rapidly heated by fine hot debris produced within it, or heated by the interaction of molten metals (as in a fuel–coolant ...
