The gallbladder holds a digestive fluid that's released into your small intestine (bile). In most cases, gallstones blocking the tube leading out of your gallbladder cause cholecystitis. This results in a bile buildup that can cause inflammation. Other causes of cholecystitis include bile duct problems, tumors, serious illness and certain infections.
Freezing level. The freezing level, or 0 Â°C (zero-degree) isotherm, represents the altitude in which the temperature is at 0 Â°C (the freezing point of water) in a free atmosphere (i.e. allowing reflection of the sun by snow, etc.). Any given measure is valid for only a short period of time, often less than a day.
Zero degrees Celsius is the freezing point for water, but the fact is that water can remain a stable liquid at zero degrees C. Zero degrees C i â¦ s also the melting point of ice, but you can have ice that remains stable at zero degrees C as well. The difference is the 'heat of fusion'.
