If...
If the temperature is zero, does that mean there is no temperature??? :wink:
Bar Harbor Maine is a beautiful place, but why is it that in the 3 times I've been here in 3 years, I've never been here between April & October? This is one of the few places I've driven to that I'd consider taking a vacation at (when it's a WHOLE lot warmer).

Zero is just a number on a scale as is zero on the Celsius scale. If the temperature is zero it simply means that there is less heat in the atmosphere than when at 32 or more heat in the atmosphere than when the temp is -15.

The only true no temperature "0" is absolute zero, or 0 Kelvin (–459.67 °F/-273.15°C). Theoretically at that point, no heat energy exists and nothing can be colder, so in essence, a ZERO temperature. At that point, according to theory (absolute 0 has never been achieved), any matter that is chilled to absolute zero will spontaneosly combust at a molecular level.
Absolute zero is still a theory because according to the laws of thermodynamics it can't really be achieved artificially. Though scientists have come close. The coldest temp achieved has been 450 pK. pK stands for picokelvin which is the exponent 10 -12.
If my math is correct that's .0000000000000450 K
That's your science lesson for today.

Thanks for the info and the "lesson of the day". I already feel I am a better person for knowing. :lol:

If nobody is around to experience/measure the "0" degree temp, then it doesn't exist. Kinda like a tree falling in the woods :lol:

And I thought Kelvin was a measurement of color. Learn something new everyday.

It's also used as a measure of color temperature.
From wikipedia:
Quote:
Color temperature is based upon the principle that a black body radiator emits light whose color depends on the temperature of the radiator. Black bodies with temperatures below about 4000 K appear reddish whereas those above about 7500 K appear bluish.
|
As for what the hell "black bodies" means:
Quote:
In physics, a black body is an object that absorbs all electromagnetic radiation that falls onto it. No radiation passes through it and none is reflected, yet in classical physics, it can theoretically radiate any possible wavelength of energy. Despite the name, black bodies are not actually black as they radiate energy as well. The amount and type of electromagnetic radiation they emit is directly related to their temperature. Black bodies below around 700 K (430 °C) produce very little radiation at visible wavelengths and appear black (hence the name). Black bodies above this temperature, however, begin to produce radiation at visible wavelengths starting at red, going through orange, yellow, and white before ending up at blue as the temperature increases.

Confused yet? :lol:

Wow, didn't expect a science lesson for complaining about it being to cold out. In fact, I learned a really important lesson. If the temperature is 0f and the wind is blowing at 20-30mph, there is no location outdoors safe for a man to take a leak. Now before everyone starts complaining, I was sitting in the receivers gravel parking lot on a dead end road against the woods after dark. I walked to the edge of the lot before 'doing the deed'.
Well, personally, if the temperature is < 45 farenheit (sp?) it's too freakin cold for me.
I called my dispatcher this morning to check in. I told him that I'd love more trips up to Bar Harbor, but only when it's 50x warmer. Then I thought about it. 50 x 0 is still 0.

Or 255.37K :lol:
