why not????? white?

[albee9]

Here's a dumb question: Why a blue spark in a car engine why not white?

[slideways...]

huh? i dont get it. people dont decide what color the spark is, but if your wondering why it happens to be that way, blue is hotter than white. so why not blue?

blue is hotter than orange.....but the sun isn't blue....HOW?

because God wanted it that way.

ask a stupid question, get a stupid answer.

thank you

Is that a serious question? Just incase it is... Temperature and heat are two different things. Temperature is what you measure with a thermometer, it does not take volume into account. Heat is the amount of thermal energy contained in an object. For example, a cup of water at 100 degrees celcius has more temperature than a gallon bucket of water at 50 degrees celcius. In the same two containers, the bucket of water has considerably more heat than the cup of water because it's volume is so much greater.

So... yes, the spark in a spark plug is a higher temperature than the sun! And there are blue stars.

yup. interestingly enough, the light wave spectrum is similar to the temp color spectrum...coincidence? i think not.

a laser beam is hotter than the surface of the sun, area for area, thus it has a higher temperature, yet it is blue. how can this be?

I'm not sure if this laser actually exists, but I'm pretty sure it does, and I'm pretty sure it's blue.

A laser beam does not have a temperature. It has energy and can cause things to heat up. It's color is insignificant. carbon dioxide laser beams are more or less invisible, but pack a hell of a wallop...

And i dont understand what you are asking. The surface of the sun is ~6000*C. the corona is much hotter, at about a million degrees. The insides of the sun is at hundreds of millions of degrees. Good for nuclear fusion. As things get hotter, they go from the red end of the spectrum to the blue end.

slideways: its not similar, it's directly related.

FALSE. x-wings shoot red lasers, tie fighters shoot green. there is a very significant reason for this.

Oook. I see what you did there.
