Auerbach attributes the Mpemba effect to differences in the behaviour of supercooled formerly hot water and formerly cold water. Chown, Marcus (June 2006). "Why water freezes faster after heating".

Humans inhabit hot climates, both dry and humid, and have done so for millions of years. Selective use of clothing and technological inventions such as air conditioning allows humans to live in hot climates. One example is the Chaamba, who live in the Sahara Desert. They wear clothing that traps air in between skin and the clothes, preventing ...
Cold shock response is a series of neurogenic cardio-respiratory responses caused by sudden immersion in cold water. In cold water immersions, such as by falling through thin ice, cold shock response is perhaps the most common cause of death. [1] Also, the abrupt contact with very cold water may cause involuntary inhalation, which, if ...
Research suggests flu viruses in high humidity can cling to water molecules and then fall out of the air. That prevents viruses from staying airborne. That prevents viruses from staying airborne.
The weather is getting chilly in many parts of the Northern Hemisphere, but cold weather doesn’t mean that you have to stop your exercise routines. I spoke with CNN wellness expert Dr. Leana Wen ...
Hypothermia has two main types of causes. It classically occurs from exposure to cold weather and cold water immersion. It may also occur from any condition that decreases heat production or increases heat loss. [1] Commonly, this includes alcohol intoxication but may also include low blood sugar, anorexia and advanced age.
Thursday's weather will feature an Arctic blast for the Midwest and Northeast and still more lake-effect snow for the Great Lakes. Cold air associated with a high-pressure area will move over the ...
It gives the water an appearance of wrinkled glass, the kind often used in bathroom windows to obscure the view, and is caused by the altered refractive index of the cold or warm water column. These same schlieren can be observed when hot air rises off the tarmac at airports or desert roads and is the cause of mirages.
