136GPa

136 GPa refers to a pressure value of 136 gigapascals. A pascal is the SI unit of pressure, defined as one newton per square meter. A gigapascal is one billion pascals. Therefore, 136 GPa is equivalent to 136 billion pascals, or 136 x 10^9 N/m^2. This is an extremely high pressure, far exceeding atmospheric pressure at sea level, which is approximately 0.1 megapascals (MPa).

Pressures on the order of 136 GPa are typically found in scientific research, particularly in high-pressure physics and materials science. Experiments conducted at such pressures are often performed using specialized equipment like diamond anvil cells, which can generate and contain immense forces over very small areas. These studies aim to understand how materials behave under extreme conditions, leading to discoveries about phase transitions, changes in crystal structure, and novel electronic or magnetic properties. For instance, 136 GPa is a pressure regime relevant to the study of certain planetary interiors, such as those of super-Earths or gas giants, where pressures can reach several hundred GPa. It also represents a significant benchmark for synthesizing or stabilizing exotic phases of matter.
