Meh - no worries. This question has become more math than science at this point! I should probably post a simplified query with nothing but the equation in the math forum. There's a math forum right? :P
That's the same formula with scale height integrated rather than calculating it separately.
That equation uses one height to determine the pressure at another height by calculating the change based on scale height. Basically it requires you to have one pressure before you can solve for the...
I have looked it up. Assuming scale height is not related to air pressure at sea level, then what is a different way to estimate the affect of temperature on air pressure at sea level?
I have figured out how to calculate the scale height - it's a pretty simple formula - but I don't know exactly how to use this value to get a more accurate estimation of air pressure at sea level.
Any suggestions?
The figure for atmospheric mass was correct.
I found the answer: temperature increase the density of the atmosphere. As density increases, the atmosphere compresses and sits closer to the surface of the planet. Gravity now has a greater effect on the mass of the atmosphere, since the mass is...
Titan's atmosphere is about 1.19 times as massive as Earth's overall. [Coustenis, Athéna and Taylor, F. W. (2008). Titan: Exploring an Earthlike World. World Scientific. p. 130.] Since only relative change matters in this context, we can say titan has 1.19 "earth atmospheric masses" - or EAMs -...
What is correlation between temperature and atmospheric pressure?
For example, why does Titan have 1.6 times the atmospheric pressure of Earth despite having pretty much the same atmospheric 'weight', for lack of better term. (Total atmospheric mass times gravity.)
EDIT: Is this the right...
I'm going to be very careful to avoid the word "greenhouse" because of the indefinite ban on discussions about climate change - I want to be clear, this isn't a topic about that.
Part 1 - some gasses in the atmosphere absorb and emit radiation in the thermal infrared range. Gases like water...
I don't think the idea is that a branch occurs when a human eye observes it - that would be silly. An "observation" occurs any time a particle interacts with another particle in a way that requires it to have a definite quantum state.
Perhaps a more kosher way of describing this phenomenon...
I apologize in advance if this has already been said. I only read the first page of this (kind of lengthy) thread, and felt the need to comment on this:
90% chance that a blue light occurs, 10% chance that a red light occurs.
Unless you know ahead of time which experimenter to choose from...
Solved the problem myself, but thought you guys might like to know the solution:
T2 = 1/((1/(T1))-Math.log(Pressure/1)*R / (Hv * 1000));
R = 8.314
Pr = Pressure you're solving for (in bars.)
Hv = Heat of vaporization for the substance in kJ/mol.
T1 = Boiling point at 1 bar of pressure...
Is there a quantifiable value for a given substance that correlates to the degree by which pressure has an effect on the element or substance melting/boiling point?
Allow me to elaborate.
If the substance in question is known (silicon dioxide, for example), how could we calculate the...
Actually, the two formulas I have seen that determine the effective temperature use albedo as a factor - I should have mentioned that.
I have to plug in an albedo of around .34 for the moon to come up with an effective temperature of 220, whereas the moon has an albedo around .11
Why is the actual mean temperature of the moon so much lower than the effective temperature?
NASA lists the effective temperature of the moon at 270.6 kelvin.
The mean temperature of the moon at the equator is 220 kelvin.
With no atmospheric effects, why is the surface temperature so much...
