Tin medal affected by tin pest. Tin pest is an autocatalytic, allotropic transformation of the element tin, which causes deterioration of tin objects at low temperatures. Tin pest has also been called tin disease, [1] tin blight, tin plague, [2] or tin leprosy. [3] It is an autocatalytic process, accelerating once it begins.
The phenomenon of freezing-point depression has many practical uses. The radiator fluid in an automobile is a mixture of water and ethylene glycol. The freezing-point depression prevents radiators from freezing in winter. Road salting takes advantage of this effect to lower the freezing point of the ice it is placed on.
Freezing is a common method of food preservation that slows both food decay and the growth of micro-organisms. Besides the effect of lower temperatures on reaction rates, freezing makes water less available for bacteria growth. Freezing is a widely used method of food preservation. Freezing generally preserves flavours, smell and nutritional ...
This article deals with melting/freezing point depression due to very small particle size. For depression due to the mixture of another compound, see freezing-point depression. Melting-point depression is the phenomenon of reduction of the melting point of a material with a reduction of its size.
If a gap exists between the solidus and liquidus it is called the freezing range, and within that gap, the substance consists of a mixture of solid and liquid phases (like a slurry). Such is the case, for example, with the olivine ( forsterite - fayalite ) system, which is common in Earth's mantle .
A few tin foil hat conspiracy theorists accuse their supermarket poultry of being lab-grown or fake. But this stringy defect is very real and it has an official name: spaghetti meat.
A major cold blast is in store for more than 30 states as a widespread arctic air outbreak will send nearly every American east of the Rockies into a deep freeze. This will be due to a polar ...
Tin has no known natural biological role in living organisms. It is not easily absorbed by animals including humans. The low toxicity is relevant to the widespread use of tin in dinnerware and canned food. [1] Nausea, vomiting and diarrhea have been reported after ingesting canned food containing 200 mg/kg of tin.
