I heard it again, and it really gets to me,"The astronauts experience a temperature change from +200C to -200C" - BOllocks"The temperature of space is NOT 10 or 50 or 100 Kelvin, it is space, it has no temperature.Temperature is a parameter of matter, it's about how atoms wobble about!, space does not wobble about!When an astronaut does a space walk energy from the sun is absorbed by his/her suit and may indeed raise the temperature then, when in shade, heat will be radiated from the suit but like a vacuum flask heat is only lost through radiation and not convected or conducted away.There, I got that off my chest! now who agrees with me?
Actually, the original quote isn't too bad. It says they "experience a temperature change," which is different from "the temperature of space is..." They're talking about the temperatures experienced by the suit, or by the astronauts if they fell out of their suits, which are certainly well-defined.
One ev is equivalent to 11604°K hence the 27KV electrons zipping down the CRT of my monitor have an effective temperature of 313,000,000°K, hot enough to generate X Rays.Thank goodness for colour screen mesh a thick lead glass!
