An antifreeze is an additive which lowers the freezing point of a water-based liquid. An antifreeze mixture is used to achieve freezing-point depression for cold environments. Common antifreezes also increase the boiling point of the liquid, allowing higher coolant temperature. [ 1 ]
Early symptoms include intoxication, vomiting and abdominal pain. [1] Later symptoms may include a decreased level of consciousness, headache, and seizures. [1] Long term outcomes may include kidney failure and brain damage. [1] Toxicity and death may occur after drinking even in a small amount [1] as ethylene glycol is more toxic than other diols.
Freezing injury may occur at temperatures below 0 degrees Celsius. Symptoms of extracellular freezing include structural damage, dehydration, and necrosis. If intracellular freezing occurs, it will lead to death. Freezing injury is a result of lost permeability, plasmolysis, and post-thaw cell bursting.
Early symptoms include a colorless appearance of the skin, a hard texture, and painless rewarming. Later, the skin becomes black and mummified. The amount of permanent damage can take one month or more to determine. Autoamputation can occur after two months. [10] Fourth degree frostbite in a homeless patient five days after freezing conditions.
However, if contact with the aerosol is prolonged the skin will freeze further and deeper layers of tissue will be affected, causing a more serious burn that reaches the dermis, destroys nerves, and increases the risk of infection and scarring. [6] When the skin thaws, pain and severe discomfort can occur in the affected area. [7]
A revelation by Julie Jensen's neighbors would confirm those suspicions. Before her death, she gave an envelope to her neighbors Ted and Margaret Wojt and told them that "if anything happens, give ...
Freezing rain does not bounce when it hits the ground like sleet, and it does not run off as warm rain does. Due to its resemblance to ordinary rain, its onset may catch some off-guard until it ...
The boiling water trick. The boiling water trick is one of the more popular experiments featured on social media during cold weather. As experimenters throw steaming water, a white cloud is left ...
