Thread: temperature

hi!

i have a little question about the weather. (i dont know if this forum is the right one). the temperature that all the newspappers, weather channels, etc show us, is measured in the shadow. for example, 31° means, on this day the temperature in the shadow will be 31°. is that right?

and other question, if we are at 1pm right under the sun, (with 31° in the "shadow") the temperature in the sun is considerably higher?

i ask that, because i made an experiment, taking the temperature in a room (27°) and then i puted the thermometer right in the sun, and the scale was in more than 55° and a friend said thats impossible.

thank you!

1: yes
2: yes, but it is cause the object in question absorbs radiation from the sun wich is turned to heat. in a shadow u dont ahve that

zelos, one more question. if the air temperature is 31°, which is the temperature that our body, skin is becoming under the sun?? it could be more than 40°??

ty!

the body temperature is 37°C, not 31. But i dontr get what youre asking. But the skin could get that hot and then our body have a very hard time cooling itself.

i mean, if the temp outside is 31°, and im under the sun, which is the temp that our body is becoming? it could be more than 40°?

Our internal temperature stays close to the target temperature of around 37 degrees. This assumes:
a) We are not ill.
b) We have taken sufficient water.

The body will happily regulate our internal temperature by heat transfer via adjusted blood flow rates and locations, and by sweating. Why do you think you turn red when you exercise vigorously. The body increases the flow of blood to the skin so that excess heat can be radiated away.

once we reaches about 40-41 we are getting very ill, and at 42 ure extremly lucky to stand up if u do. ure most likly dead then

then what is thermoregulation?

Thermoregulation is the ability of an organism to maintain its temperature within an optimal operating range. It is what I described in my post further up the page. You can find a fuller discussion of it on wikipedia:

Thanks... for guiding me..
