It's the same loop.
Go find a reference for the density of dry air for example. They tell you it's for a given T and P because it varies with both. So if you state a pressure and the density, you are stating the temperature.

So, your soft drink is not safe.
Does this mean we have to outlaw carbonated soft drinks?

seems as if a key component is being left out like the different rotations and chemical makeup of the core of the earth and venus. Venus also doesn't have a magnetosphere to protect it against solar radiation.
Fun fact we know more about how the systems in space function than we do the human brain... so in a parallel universe that our brain can't comprehend venus is pleasant like caribbean beaches full of beautiful women. The maths says its true

Why does this matter? People exhale CO2. So the more people on the planet the more O2 is used and CO2 produced. To stop global warming we need population control.
I suggest we start by aborting all liberal babies so no more liberals are born. I see it as a win win. We stop global warming (liberals are happy) and we kill unborn babies (liberals are happy). The conservatives will be happy once all the liberals are gone.

Makes sense, based on name alone.

Can I impose on you to do that math for this chem/bio major?
The ideal gas law can be rearranged as a function of density (d) to drop the volume term.
So PV = nRT solved for T and include density ---->
T = P/Rd/n or T = Pn/Rd
This is the mean temperature (T in kelvin), mean pressure (P in KPa), mean density (d in kg/m^3) and the universal gas constant (R at 8.314 J/mol-K).
Mean surface pressure of Venus is 92.1 atmospheres = 9332 KPa.
Mean surface density of Venus is 67 kg/m^3.
Mean moles is 43.45
T = 9332*43.45/8.314*67 = 727.91 K = 454.76 C
Wiki says the following:
LINK
So the ideal gas law is off by 7.25 degrees C through this exercise. But that can be attributed to an inaccurate density published in wiki. If the density were 66.43 kg/m^3 instead of the documented 67 kg/m^3 the ideal gas law would have nailed the surface temperature published in wiki.
ETA: Here is a quote from a scientific paper on the density of Venus atmosphere:
quote:
Atmospheric density at the surface is about 65 kg m-3
LINK
So there is a little dependency between Wiki and this paper.

So what was your terrestrial solution?
That was the solution for temperature at elevation zero on Venus.
As you increase in elevation on Venus you decrease in temperature and pressure just like on earth.

If so, please provide a link to said proof.
The claim that CO2 increasing from 0.03% to 0.04% of atmospheric composition is causing 'man made global warming' is pretty laughable, especially when that idea is propagated by 'scientists' who would not have a job is they did not believe in man made global warming. As if CO2 is the only driver of temperatures.
If you really want to get a kick, google climate models and how they are made. Models are 'tuned' to fit historical data trends when the numbers are not matching up. Also, they have a big problem with third parties being able to replicate said models, since the people who made them are the only ones who know how they work (black box).

So it's just a circle to solve for the temperature after that.
It’s not a circle if the input values were acquired independent of the IGL.
I got the numbers from wiki which is linked to scientific references. Now if the scientific references obtained the pressure and density values from the IGL then yes we are going around in circles.
But the irony of that would be an implicit agreement by the scientific authority that the IGL is a valid model for predicting planetary surface temperatures.

Waaaaayy over thinking this.
The "dangers" of "Climate Change" is a money grab and a scam.
There is nothing wrong with the environment.
Just sayin'.

I am loving these threads so far. Not a single one has been answered yet despite our resident genius hoi polloi scattershotting insults and vague nonsense buzzwords.

atmospheric and planetary science doesn't care what you learned in Chem E.

No, it does make the circle.
The IGL model says density is PM/RT. M and R constant. You tell it a pressure and a density, it has to be the temperature you end up getting.
quote:

I know you did. The problem is the IGL says the density will be some value for a given T, P, and molar mass. If the pressure was higher at the same temp, the density would be too. If the temp was lower at the same pressure, the density would have to be lower too.

No. It's an agreement that the density of a gas changes as temperature and pressure does. Which, you know, it does.

I think its more of a combo of Chem E, Mech E and some Navier-Stokes all rolled up into one.
Regardless, an increase in CO2 from 0.03% to 0.04% isnt affecting shite
Posted on 6/4/19 at 8:17 pm to hubertcumberdale
wrong!
it is affecting things like plants. more CO2 will effect plant and animal evolution. There was a time on earth when there was a crapload more CO2. The successful species adapted by having bigger stomata and bigger leaves to absorb more CO2. before long there will be gigantic leaved trees everywhere with a bunch of badass gigantic frogs eating gigantic mosquitos. it's only a matter of time.

I may be off here, but isnt this why you introduce z (compressibility factor) into the equation, which becomes the real gas law rather than ideal to account for the changing density at different P&Ts?
