THE work of Oldham and Ubbelohde 1 suggested that the melting point of mixtures of dipolar compounds may be much lower than predicted by the Le Chatelier–Schröder (or Hildebrand) equation 2 if one ...

Beneath the ocean, massive tectonic plates collide and grind against one another, which drives one below the other. This powerful collision, called subduction, is responsible for forming volcanic arcs ...

FRICTION burns. And the friction of the air on something travelling at five times the speed of sound burns hot. The leading edge of such an object can easily reach a temperature of 3,000°C.

The melting point range of a substance is the temperature range from which the first crystal starts to melt, to the temperature at which the last crystal finishes melting. Key fact An impure substance ...

STATE COLLEGE, Pa., April 20 (UPI) --What controls cocoa butter's melting point? A single genetic trait. And researchers at Penn State say they've found it. Scientists say their discovery will allow ...

A new study changes our understanding of how volcanic arc lavas are formed, and may have implications for the study of earthquakes and the risks of volcanic eruption. Beneath the ocean, massive ...
