Â­. Â­Dry ice is frozen carbon dioxide. A block of dry ice has a surface temperature of -109.3 degrees Fahrenheit (-78.5 degrees C). Dry ice also has the very nice feature of sublimation -- as it breaks down, it turns directly into carbon dioxide gas rather than a liquid.
The time for a broken collarbone to fully heal depends on the severity of the injury. In children, complete healing may take as little as three to six weeks. In adults, six to 16 weeks or more are often necessary for a collarbone to heal solidly.
Other frequent causes are falls and car, motorcycle or bike accidents. The time for a broken collarbone to fully heal depends on the severity of the injury. In children, complete healing may take as little as three to six weeks. In adults, six to 16 weeks or more are often necessary for a collarbone to heal solidly.Unfortunately, during that time there is no way to completely immobilize a collarbone fracture to keep it from moving and, thus, speed healing, as can be done using a cast on other broken bones, such as a wrist, arm or leg. broken collarbone is a very common injury, particularly in children and young adults. One reason is that young people are more likely to participate in sports that increase the risk of a broken collarbone, such as football, basketball, wrestling, rugby, hockey, skiing and snowboarding.
