Is it safe to run when the temperature is below zero?
This information is by a training coach: It is perfectly safe to run through the winter as long as you take a few precautions. There is no danger to your lungs because the cold air you breathe is warmed by the time it gets into your lungs. You need to wear proper running attire. Recommended are going to your area's running specialty stores where they can help you figure out the proper gear. You want to run with light layers of clothes that breathe instead of running with bulky sweat clothes. When running in very cold weather, try to run into the wind at the beginning and end your run with a tailwind. If it is really windy and cold, put Vaseline on your face to protect it. If you start out with a tailwind, you will overheat and be chilled when you turn around and head back into the wind. Also, be very careful of your footing if there is any ice or snow on the ground. If there is, shorten your stride and take short, choppy steps. Be particularly careful if you are an early morning runner because it is hard to see slippery patches of ice. Keep in mind that the first 4 - 5 minutes in cold weather is uncomfortable, but once you get going you will become very warm.

The ideal temperature of your room should be between 68-71o F You should not go below 50o or above 82o F.
Yes, regularly and routinely.
This happen to my cousin's vehicle one cold winter and what happened was that since it was so cold the fuel lines frosted due to gasoline has water in it. What I ended d…oing was pouring in his gas tank a bottle of gas dry. An hour later the vehicle started up. It unfrosted the fuel line and ever since he poor a bottle of gas dry every time the temperatures goes below freezing. No more problems. Try it…
The capacity of a heat pump declines as the outside air decreases and more frequent defrost cycles are required. A "balance point" calculation is used to determine the t…emperature at which the HP can no longer provide all the heat required to heat the space. At this "balance point" strip heat or in the "dual-fuel" application, a furnace is brought on to supplement the system. There is then a point even lower in temperature where the compressor should be "locked out", as it is no longer cost effective to operate. Yes heat pumps work when it is below freezing. lc
Below zero is Freezing.
south and north pole
hypothetically it can. According to thermodynamics if temperature is dropped below -273 C (0 K) the volume becomes negative, which is not possible in our universe. But (hypo…thetically) there are infinite parallel universes consiqutively positive and negative. The positive one consists of matter and the negative of antimatter(proved practically at CERN) . volume of matter is positive and that of antimatter is negative. So by the time the temperature is dropped below 0 K all the matter is converted into antimatter and it eventually goes in another universe.
One to two days per year, on average.
Although 98.6 has long been set as the "normal" body temperature, body temp can fluctuate yet still be within normal range for that person. For example, one person may consist…ently run 97.6 and be okay. Another person may feel very feverish with a temp of 99.0, just 0.10 higher than "normal". However, body temp below 96 requires medical intervention.
Birds that breed in Antarctica in sub-zero, extreme cold temperatures have adaptive behaviours to insure the preservation of their species. For example, King and Emperor Pen…guin females lay their eggs and immediately scoop them up and position them on the tops of their webbed feet and flop their belly fat over the eggs to keep them warm. After laying the eggs, and when the males return from feeding in the ocean waters, the males find their mates, and the egg is transferred to the tops of the males' webbed feet, where they flop their belly fat over the eggs. Then, the males huddle in creches and move together slowly with their backs to the wind, to survive and warm the eggs enough to hatch. After they hatch, the females return, fully regained of their pre-birth weights, and take over the chicks. The males are then free to eat after many months of hatching work. You can see a photo, below, of a King Penguin creche protecting their chicks from the extreme cold, until the chicks' molts are complete and they can take to the water and feed themselves.
no because people need to get home so they can be warm.
