SUMMARY

Pressure can indeed be less than 1 atmosphere in a grounded container on Earth if air is removed and the container is sealed. Additionally, if the temperature inside the sealed container decreases, the pressure will also drop below 1 atmosphere, assuming the container is rigid. This phenomenon is exemplified by common light bulbs, which operate under similar principles of pressure and temperature changes.

PREREQUISITES
  • Understanding of gas laws, particularly Boyle's Law
  • Knowledge of the relationship between temperature and pressure in gases
  • Familiarity with the concept of atmospheric pressure
  • Basic principles of thermodynamics
NEXT STEPS
  • Research Boyle's Law and its applications in real-world scenarios
  • Study the ideal gas law and its implications for pressure and volume
  • Explore the effects of temperature changes on gas pressure in sealed containers
  • Investigate practical applications of low-pressure environments, such as vacuum sealing
USEFUL FOR

Students in physics, engineers working with pressure systems, and anyone interested in the principles of thermodynamics and gas behavior.

can pressure be less than 1 atm in a container kept on the ground of the Earth , i am getting puzzled , pl. help!

yes is we remove air from it and seal it.

thanks cragar!
 
no problem
 
If you seal the container, and then the temperature cools, that would make the inside pressure less than 1 atmosphere.

Assuming container is rigid.
 
A common light bulb is a good example.
