Meteorology atmosphere temp question

Click For Summary
SUMMARY

A liquid thermometer cannot register a temperature of -273° C under any circumstances, as no known fluids can reach that temperature. The discussion highlights the importance of understanding the difference between heat and temperature, particularly in extreme atmospheric conditions. The question revolves around the atmospheric pressure and its effect on temperature readings, suggesting that at very low pressures, the behavior of thermometers may differ significantly. The subdivisions of the atmosphere play a crucial role in understanding these phenomena.

PREREQUISITES
  • Understanding of thermodynamics and the principles of temperature measurement.
  • Knowledge of atmospheric pressure and its variations in different atmospheric layers.
  • Familiarity with the concept of heat versus temperature.
  • Basic meteorological concepts regarding the structure of the atmosphere.
NEXT STEPS
  • Research the principles of thermodynamics, focusing on temperature and heat.
  • Study atmospheric pressure variations and their effects on temperature readings.
  • Learn about the different layers of the atmosphere and their temperature characteristics.
  • Explore the limitations of liquid thermometers and alternative temperature measurement methods.
USEFUL FOR

This discussion is beneficial for students studying meteorology, physics enthusiasts, and anyone interested in the principles of temperature measurement in extreme 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.
