When was the American Chemist born, who introduced the first Ice-type model?
Linus Pauling Linus Carl Pauling (February 28, 1901 – August 19, 1994) was an American chemist, biochemist, peace activist, author, and educator. He published more than 1,200 papers and books, of which about 850 dealt with scientific topics. "New Scientist" called him one of the 20 greatest scientists of all time, and as of 2000, he was rated the 16th most important scientist in history.
Ice VII Ice VII is a cubic crystalline form of ice. It can be formed from liquid water above 3 GPa (30,000 atmospheres) by lowering its temperature to room temperature, or by decompressing heavy water (DO) ice VI below 95 K. Ordinary water ice is known as ice I, (in the Bridgman nomenclature). Different types of ice, from ice II to ice XVI, have been created in the laboratory at different temperatures and pressures. Ice VII is metastable over a wide range of temperatures and pressures and transforms into low-density amorphous ice (LDA) above 120K. Ice VII has a triple point with liquid water and ice VI at 355 K and 2.216 GPa, with the melt line extending to at least 715 K and 10 GPa. It can also be created by increasing the pressure on ice VI at ambient temperature.
