SUMMARY

The discussion centers on solving for temperature (T2) using the Ideal Gas Law, specifically the equation P1/T1 = P2/T2. The user initially calculated T2 as 50 using Celsius values, but the correct answer is 323 Kelvin. The key error identified was the failure to convert Celsius to Kelvin before performing the calculations, highlighting the importance of using absolute temperature in gas law equations.

PREREQUISITES
  • Understanding of the Ideal Gas Law and its components (P, V, T, n).
  • Knowledge of temperature conversion between Celsius and Kelvin.
  • Familiarity with algebraic manipulation of equations.
  • Basic principles of thermodynamics.
NEXT STEPS
  • Learn about the Ideal Gas Law and its applications in real-world scenarios.
  • Study temperature conversion techniques, specifically between Celsius and Kelvin.
  • Explore common mistakes in gas law calculations and how to avoid them.
  • Investigate the implications of using absolute temperature in scientific calculations.
USEFUL FOR

Students studying chemistry or physics, educators teaching thermodynamics, and anyone interested in mastering the Ideal Gas Law and its applications.

Followed is my working

P1/T1=P2/T2
T2=(T1/P1)*P2
=(T1)*(P2/P1)
=25 * 2
=50

But the answer is D. 323,
may I know what is my problem?

Yes, for the ideal gas law you should measure temperature in degrees kelvin. Convert C to K, solve the problem and convert K to C.
 
I see, thanks for help!
