Temperature vs time plots, showing the Mpemba Effect. 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.
Apparent temperature, also known as "feels like", [1] [2] is the temperature equivalent perceived by humans, caused by the combined effects of air temperature, relative humidity and wind speed. The measure is most commonly applied to the perceived outdoor temperature.
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 ...
At least 246 Texans died during last February’s winter storm. More than half suffered from hypothermia or frostbite. Here’s how to protect yourself.
The first stage of cold water immersion syndrome, the cold shock response, includes a group of reflexes lasting under 5 min in laboratory volunteers and initiated by thermoreceptors sensing rapid skin cooling. Water has a thermal conductivity 25 times and a volume-specific heat capacity over 3000 times that of air; subsequently, surface cooling ...

The cold temps will be replaced by much milder air next week, but the warmth will come after a frigid, snowy weekend for portions of the northeastern U.S. Up to a foot of snow is expected near the ...
This could be producing rain on the ground or the possibility of freezing rain if the temperature is below freezing. The accompanying image shows how such an artifact can be located with a cross-section through radar data. [8] [9] The height and slope of the brightband will give clues to the extent of the region where melting is occurring. Then ...
