SUMMARY

The discussion centers on the Ideal Gas Law and the implications of doubling temperature and volume under constant pressure conditions. Participants clarify that temperature must be measured in Kelvin for accurate calculations, emphasizing that a temperature change from 25°C to 50°C does not constitute doubling, whereas a change from 100 K to 200 K does. The correct answers to the posed problem are identified as statements 1 and 2, while statement 3 is deemed incorrect.

PREREQUISITES
  • Understanding of the Ideal Gas Law (PV=nRT)
  • Knowledge of temperature scales, specifically Kelvin
  • Familiarity with the concept of constant pressure in gas laws
  • Basic algebra for manipulating equations
NEXT STEPS
  • Study the Ideal Gas Law applications in real-world scenarios
  • Learn about the significance of temperature conversions between Celsius and Kelvin
  • Explore the effects of pressure changes on gas volume and temperature
  • Investigate the relationship between gas laws and thermodynamics
USEFUL FOR

Students studying physics or chemistry, educators teaching gas laws, and anyone interested in the principles of thermodynamics and gas behavior.

I chose 1&2, but all three are correct. I thought for a constant pressure, if temperature is doubled, then the volume would doubled too? As P=V/T ?

3 is not a correct statement. Change from 25°C to 50°C is not doubling the temperature. Change from 100 K to 200 K is.

Sorry I typed wrongly, I chose 1,2&3, but ans. is 1&2.
oh.. Right, they must be in Kelvins. Thanks again :smile:
