Coolers are equipped with a very elegant temperature regulation mechanism. A thermocouple implanted in the cooler insulation detects temperature gradients between the interior and exterior surfaces of the cooler. If the initial gradient is measured to be rising in temperature toward the center of the cooler, the cooler insulation automatically orients itself to reflect heat back toward the center of the cooler, thereby keeping the contents warm.
Conversely, if the temperature gradient detects that the contents of the cooler are cold, the insulation reverses its orientation to deflect exterior heat and preserve the colder temperatures on the inside of the cooler.
All of this is accomplished through the use of a non-newtonian polymer embedded with thermo-sensitive alloys which alter their magnetic polarity to align with termperature gradients. As the temperature gradient changes so does the magnetic polarity which alters the insulation alignment in the appropriate direction.
A competing theory is that coolers do not "know" to keep food hot or cold, rather they are insulated and there-by stablilize the temperature and prevent it from changing. If you place hot items in an insulated container they will stay hot, cold items will stay cold.
One use for ice is to put it in a drink to keep it cool, and you can also use it in an ice pack/cold compress. The one other use i know is to keep perishable food from going bad.
hummm i dont really know i think it is food
It depends which country you wish to know about. In Britain almost nobody had a refrigerator so those with cellars would keep their food in cabinets with wire mesh on the sides to let cool air in and mice out. Also food was scarce with not enough available to keep for long periods and people had to shop every day for essentials.
warmer countries. You should know this. Butterflies don't come out in the winter or cold places. Are you crazy!?!!
if you have a cold and you have mold that's how you will know when your food is getting old.( like stinky cheese with a cold from mold whos getting old!!!) :p
The WD31EC - Avanti Tabletop Thermoelectric Water Cooler/Heater has seperate hot and cold faucets. So the same water could be heated and cooled over and over and over.
buy her food and if she gets happy, keep her
Cooler air is more dense than warmer air, that means that for a unit of volume cooler air will be heavier.
to keep your feet warm But Not just that, If Your Feet Get to cold You can have Pains In your Stomach. I don't know why You get a stomach acks But that's what happens.
If dogs vocalized names for seasons they'd refer to the feel of the time.Human speech evolved this way, by sounding out the noises they heard, and then by inventing sounds for feelings, internal and external, eventually becoming sophisticated speech as we now know it.So, wild animals might refer to seasons as warm, hot, cooler, cold, in the northern hemisphere, and warm-wet, hot-wet, hot-dry, warm-dry, in the southern.They'd probably incorporate their food into their sounds for seasons, so, in the north: warm-eggs-smallmeat; cold-digupfood-findsleepingfood; hot-fish-bigmeat; cooler-foodontrees-foodonground-movingmeat......they'd have separate word for small parts of seasons which specifically referred to their community; so: warm-findmate; hot-feedbabies; cooler-teachbabies; cold-findgoodshelter...and so on.
In the Fridge you should know, to always keep the meats below. Keep food safe – clean, cook, cover, and chill. Make food simple and let things taste of what they are. No Safety, Know Pain.
yes they gather food for the winter because it is to cold for them to go outside in winter, i can not believe people did not know that.
