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.
Water molecules have more energy in liquid form than in solid form. As the temperature of the liquid becomes lower, the energy is reduced, which causes the water molecules to slow down. When the temperature reaches freezing level, the molecules stick together to form solid ice. However, the molecules are still in motion. There is more to water freezing than just getting cold.
