Meteorology atmosphere temp question

AI Thread Summary
A liquid thermometer cannot register -273° C while the air temperature is 500° C due to the physical limitations of fluids at extreme temperatures. The discussion highlights the importance of understanding the difference between heat and temperature, particularly in low-pressure environments. It suggests that exploring atmospheric layers could provide insights into temperature variations. The inquiry emphasizes that no liquid can exist at absolute zero, making the scenario theoretically impossible. Overall, the conversation centers on the complexities of temperature measurement in varying atmospheric conditions.

Homework Statement



Could a liquid thermometer register a temperature of -273° C when the air temperature
is actually 500° C ? Where would this happen in the atmosphere, and why ?


The Attempt at a Solution



I have no idea. If someone could just give some possible tips on what it may be. I'm thinking that it could register a different temperature and it may have something to do with atmospheric pressure.

Maybe it helps to find the subdivisions of the atmosphere in wikipedia, finding a ...sphere with matching temperatures.

But the thermometer question is doubtful, as no fluids can reach that temperature. It should have said: Could a [strike]liquid[/strike] thermometer register a temperature of -273° C
 
The intention of the problem (when you look beyond the nonsensical idea of a liquid thermometer measuring a temperature of -273) hinges on the difference between heat and temperature, and how it would present itself at very low pressures.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
