SUMMARY

The discussion centers on determining the acceptable error in temperature measurement that would result in a pressure measurement error of no more than 5%. Participants suggest utilizing the Ideal Gas Law (PV=nRT) to analyze the relationship between temperature and pressure. The conversation emphasizes the importance of precise temperature readings to maintain accuracy in pressure measurements, particularly in scientific and engineering applications.

PREREQUISITES
  • Understanding of the Ideal Gas Law (PV=nRT)
  • Basic knowledge of thermodynamics
  • Familiarity with measurement error analysis
  • Experience with pressure and temperature measurement tools
NEXT STEPS
  • Research the Ideal Gas Law and its applications in real-world scenarios
  • Study measurement error propagation techniques
  • Explore thermodynamic principles related to gas behavior
  • Learn about calibration methods for temperature and pressure sensors
USEFUL FOR

Scientists, engineers, and students in physics or engineering disciplines who are involved in experiments or applications requiring precise temperature and pressure measurements.

Somebody who can explain the question
How big a error must there be at the temperature for the error on the pressure measurement is not more than 5 % ?

thanks in advance

Hello
What do you think would be an appropriate answer? How could you go about finding the result of changing pressure by 5%? (Use one of the formulae that you would have in your toolbox.)
 
I think that one could use the ideal gas equation, but are not quite sure
