A laser is not a blackbody radiator. Do you even know the formula that website uses? And by the way, I'm not asking questions because I don't know this stuff, I'm asking questions because it shows how inconsistent and contradictory your logic is, and you're cooperating nicely. (Except for the brief period you ran away from answering) (by the way, you still haven't answered why you had to account for sun distance, if sun distance doesn't matter for venus' temperature)
-
I meant out of the total heat flux. Why are there 2 answers? It's because you're completely making it up.
-
Great, then show your calculation, please. Bill, she just claimed to calculate the temperature of an electromagnetic wave. Photon energy is measured in eV - electronvolts. Ever heard of this guy called Einstein?
-
Absolute bullshit calculation. You can't convert W/m^2 to temperature. Those are completely different quantities. Converting the weight of a car to watt hours makes more sense than that.
-
Then why did you have to account for sun distance? According to you it makes a difference of 1 degree.
-
So it's mostly solar then, you just contradicted yourself. Thanks for admitting that you're wrong.
-
If Venus' heat was mostly from internal heat, then you don't have to account for sun distance, right? So why? You say one thing, then do something completely different, probably because it's bullshit.
-
I actually looked this up (yes, I'm bored) and boy it is crazy His theory is: around the 15th century BCE, Venus was ejected from Jupiter as a comet or comet-like object Venus must be rich in petroleum and hydrocarbon gases (it's not) "Velikovsky arrived at these proposals using a methodology which would today be called comparative mythology – he looked for concordances in the myths and written histories of unconnected cultures across the world" - i.e he used fiction, no hard evidence You do know that before 15th century BCE, Venus was already known by ancient people in its current position right? Ancient Egypt was around way before that.
-
Any evidence for that? No, the crickets are from you. NASA's explanation of my question is the temperature difference between Venus and Earth is due to the greenhouse effect.
-
Oh well, I'll take that as her running out of answers. She's just reduced to running away and looking for the next person to scam.
-
Still can't answer my questions, huh?
-
Zoe, it's my laser and it's 120 watts power output, beam diameter is focused to as small as I can make it - usually around 0.1mm. But you're avoiding my simple questions. Edit: temperature is kept to around 40 degrees C by water cooling (water chiller) - if it went about 100C then the water would boil.
-
Nobody said that, so stop making things up. You can't answer simple questions - HOW and WHY is Venus' history different from earth's?
-
No it doesn't, it just cools down slower. This may be the crux of your misunderstanding.
-
What? Stop making things up and answer my questions. I didn't, I'm just asking WHY they should be different, and HOW it's different. All you can muster is "they're different" and give no explanation or proof. Pathetic.
-
Interesting random and chaotic experiment design with no reasoning given for the choices whatsoever. Waiting on the answers for: how photons failing to warm something up isn't a violation of conservation laws how venus' and earth's histories are different
-
So what happens if you fire that laser at a hotter object - like a plasma? Where does the energy go? You said "the photon dies and fails to warm it up" - where does the photon energy go? It's a violation of conservation laws. You've never answered this question and I asked it a long time ago. Edit to add: you've never answered my question about how Venus' and Earth's histories are different either. Looks like you're running out of answers.
-
There's also this thing called an air conditioner...I'm sure you've heard of it? How does it cool down a car? Same with fridges and freezers. They actively pump heat OUT of things to make them cold. That would be impossible if energy only flowed from hot to cold.
-
I actually have a CO2 laser (120 watts) that I use water to cool, so it definitely stays colder than 100C. I can volunteer this laser for the experiment, provided that we swap the metal plate with a thin sheet of paper, and that ZP stand behind it. If the sheet of paper never reaches 100C, there should be no problem right?
-
Venus is literally the closest planet, and we're in the same solar system. How is their history different? You're answering with very short vague answers, because you have no idea what you're on about.
-
That's not a reason. Why would they have different internal heat? They're both rocky planets with similar silicate composition. They're also very close in size and mass.
-
Wow, this is really the stupidest thing I've heard so far. You must have gotten brain damage after the module on entropy.
-
Hey ZP you've conveniently forgotten my question, all you needed was a number between 0 and 50. Anyway, you're now on record, TWICE: So if it's mostly sun, why does Venus suddenly become hot "mostly because of internal heat"? So earth is hot because of "mostly sun" but venus is hot because of "mostly internal heat"? What makes Venus's internal heat so much hotter than earth? Why the inconsistency?
-
How much? Give percentages, even rough estimates. 80/20? 70/30?
-
Either it's mostly sun or mostly internal heat. It can't be both. "Mostly" being at least 50%, which is it?
