200GPa

200 GPa refers to a pressure of 200 gigapascals. A pascal is the SI unit of pressure, defined as one newton per square meter. A gigapascal is one billion pascals. Therefore, 200 GPa is equivalent to 200 billion newtons per square meter. This is an extremely high pressure, significantly exceeding the pressures found in terrestrial environments. For comparison, the pressure at the Earth's core is estimated to be around 360 GPa, and the pressure at the bottom of the deepest ocean trench is approximately 110 MPa, which is 1,000 times less than 1 GPa.

Pressures of 200 GPa are typically encountered in specialized scientific research, such as high-pressure physics experiments conducted in diamond anvil cells. These experiments aim to study the behavior of materials under extreme conditions, which can lead to the discovery of new phases, properties, and even elements. For instance, materials subjected to such immense pressures can exhibit changes in their crystal structure, electronic conductivity, and magnetic properties. Understanding these high-pressure behaviors is crucial for fields like geophysics, materials science, and planetary science, as it helps us comprehend the conditions within planets and other celestial bodies. The development of technologies capable of generating and measuring such pressures is essential for advancing our knowledge of matter under extreme states.
