Is Absolute Zero Possible and What Would Happen at 0 Pressure?

Click For Summary
SUMMARY

At 0 atm, classical physics suggests that there is no gas present, which implies that temperature cannot be defined in the traditional sense. However, the discussion posits that at 0 pressure, absolute zero could theoretically exist, leading to the freezing of all materials due to diffusion. This scenario raises significant implications for the Universe, potentially resulting in a complete freeze. The conversation highlights the complexities of defining temperature in the absence of gas.

PREREQUISITES
  • Understanding of thermodynamics and the concept of absolute zero.
  • Familiarity with gas laws and pressure-temperature relationships.
  • Basic knowledge of diffusion processes in materials.
  • Awareness of the implications of extreme conditions in physics.
NEXT STEPS
  • Research the principles of thermodynamics, focusing on absolute zero and its implications.
  • Study the ideal gas law and its limitations at low pressures.
  • Explore the effects of diffusion at extreme temperatures and pressures.
  • Investigate the theoretical implications of a universe at absolute zero.
USEFUL FOR

Students of physics, researchers in thermodynamics, and anyone interested in the theoretical implications of extreme conditions in the Universe.

Homework Statement


What is the temperature at 0 atm? Also what is its significance?
 
Physics news on Phys.org
0 atm implies no gas present, so classically it couldn't have a temperature.
It would have the temperature of the surrounding pressure vessel but that might not be a useful definition.

Interesting. However... at 0 pressure, there may be 0 temperature, which could theoretically exist,though it would cause all materials around to freeze due to diffusion. This might cause the Universe to freeze, though.
oh, btw, I am an amerature at this :frown: i don't really know what I am talking about.
