Depending on the temperature, it becomes dense-phase (which for a single component system is analgous to super-critical).

On reflection, GoodGame's assertion that I am referring to gasses has some validity. I should stipulate that I am not referring to things like alloys. I am referring to multi-component mixtures in vapour-liquid equilibrium. I am talking about the phase diagram for such a mixture, and what the maximum pressure at which liquids can be present is called.

 

[ainwood]

Its been 72 hours. Correct answer is cricondenbar. Equivalent for temperature (highest temperature above which liquids cannot be present) is cricondentherm.

What are the 10 largest (by volume) objects in the solar system (that we know of) in order from largest to smallest?

Oh and for mastermindish twist, I will state how many are on the list, and how many are in the correct position.

 

[sepamu92]

1. Sun
2. Jupiter
3. Saturn
4. Neptune
5. Uranus
6. Earth
7. Venus
8. Mars
9. Mercury
10. Xena (or whatever they decided to name it)

 

[Perfection]

8 of the objects on your list should be on the list, 6 of the objects are in the correct order.

 

[History_Buff]

1. Sun
2. Jupiter
3. Saturn
4. Neptune
5. Uranus
6. Earth
7. Venus
8. Mars
9. Titan
10. Ganymede

I know it's two moons, because I was asked this back in grade 12 for some reason.

 

[Mise]

I think Titan's bigger than Venus, based on what Perf said ^^

[History_Buff]

Ohh, for starters, Uranus is definitely bigger than Neptune. As for what else is out of order, it's gotta be the last 2.

The vacuum is the largest (if you can call it an object)


You should have said 'by mass', not by volume.

 

[Perfection]

The vacuum is the largest (if you can call it an object)

I don't think you can. I suppose compact body would be a better term, though.

You should have said 'by mass', not by volume.

Why?

 

[ainwood]

Why?

Because the volume of the solar system is much larger than the volume of the bodies within it.

 

[Perfection]

Yeah, well everyone figured it out so and and

And really, mass wouldn't prevent all the issues, because pedanticites coulda said crap like Kuiper belt and whatnot.

The key here is the implicit understanding that object means compact body that everybody figured out.

Alright, here we go:

In a very basic way, how do GPS receivers estimate the effect of atmospheric interference on the recieved signal?

 

[brennan]

Some kind of correction based on local meteorological reports?

 

[Perfection]

Using math?

 

[Mise]

Do the satellites send out a "signal" signal (...something like a single-frequency, standard amplitude signal, at standard intervals in time, outside of the frequency range of the "data" signal) that is known to the GPS receiver? Any deviation from this known signal (noise, assumed to be as a result of atmospheric interference) can be used to estimate the effect of atmospheric interference.
