article_snippet: This type of CO2 is created when liquids and gases reach liquids and gases temperature and pressure thresholds, creating a supercritical fluid that has features of both a liquid and gas.
article_snippet: Carbon dioxide becomes supercritical when its temperature exceeds 305 degrees Kelvin (32°C) and its pressure goes beyond 72.9 the standard atmosphere at sea level.
article_snippet: Study co-author Professor Schulze-Makuch and his team compared enzymes in carbon dioxide and in water, and found that they were more stable in supercritical CO2.
