She also believes that exposure to moderately high temperatures induces epigenetic changes that can help corals withstand very high temperatures.
They decompose at moderately high temperatures (55° C [131° F]) and require protection against moisture.
It directly combines nitrogen from the air with hydrogen under extremely high pressures and moderately high temperatures.
Subsequent studies have shown, however, that many, if not all, of the rocks are metamorphic, formed by recrystallization at high pressures and moderately high temperatures.
Haber succeeded in getting nitrogen to combine with hydrogen by the use of high pressure, moderately high temperatures, and a catalyst.
Molten sulfur is burned to form sulfur dioxide, which is cooled, then oxidized, usually in the presence of pellets of porous siliceous material impregnated with vanadium pentoxide and a potassium compound, to form sulfur trioxide at moderately high temperatures.
About 1909 the German chemist Fritz Haber ascertained that nitrogen from the air could be combined with hydrogen under extremely high pressures and moderately high temperatures in the presence of an active catalyst to yield an extremely high proportion of ammonia, which is the starting point for the production of a wide range of nitrogen compounds.
Grilling takes minutes rather than hours, and is done directly over the heat at moderately high temperatures (220ºC or more), making it ideal for thinner pieces of meat such as hamburger patties, racks of lamb and beef steaks no more than an inch thick.
The rolling experiment was performed at moderately high temperatures (450, 550 and 650 °C).
This is true even for long annealing times at moderately high temperatures.
