The Mpemba effect is the name given to the observation that a liquid (typically water) that is initially hot can freeze faster than the same liquid which begins cold, under otherwise similar conditions. There is disagreement about its theoretical basis and the parameters required to produce the effect.
Freeze avoidant: These species are able to prevent their body fluids from freezing altogether. Generally, the AFP function may be overcome at extremely cold temperatures, leading to rapid ice growth and death. Freeze tolerant: These species are able to survive body fluid freezing. Some freeze tolerant species are thought to use AFPs as ...
During the final stage of freezing, an ice drop develops a pointy tip, which is not observed for most other liquids, and arises because water expands as it freezes. [10] Once the liquid is completely frozen, the sharp tip of the drop attracts water vapor in the air, much like a sharp metal lightning rod attracts electrical charges . [ 10 ]
A newly identified colon cancer gene may drive the disease by making the environment in the vicinity of tumors more hospitable to them, researchers say. Why does colon cancer grow so fast? Study ...
Cancer cannot be treated by restricting food intake and so supposedly "starving" tumors. Rather, the health of people with cancer is best served by maintaining a healthy diet. [302] The common cold and the common flu are caused by viruses, not exposure to cold temperatures. However, low temperatures may somewhat weaken the immune system, and ...
The World Health Organization's cancer agency released a statement on Wednesday saying that 'very hot' beverages may be cancerous. The World Health Organization's cancer agency released a ...
During the scan, the doctor noticed she had a mass on her ovary. At first, doctors thought she had a simple ovarian cyst, which are fairly common, often associated with the menstrual cycle and ...
Leidenfrost droplet Demonstration of the Leidenfrost effect Leidenfrost effect of a single drop of water. The Leidenfrost effect is a physical phenomenon in which a liquid, close to a solid surface of another body that is significantly hotter than the liquid's boiling point, produces an insulating vapor layer that keeps the liquid from boiling rapidly.
