SUMMARY

The discussion centers on the calculation of temperature in a sealed 3.00-L tank containing air at an initial pressure of 3.00 atm and temperature of 20.0°C. The pressure drops to 1.00 atm, prompting the need to determine the final temperature using the isochoric process formula P/T=const. The correct calculation reveals that temperature must be expressed in Kelvin, leading to a final temperature of 6.67°C when converted from Kelvin.

PREREQUISITES
  • Understanding of the ideal gas law and its applications
  • Knowledge of temperature conversion between Celsius and Kelvin
  • Familiarity with the concept of isochoric processes in thermodynamics
  • Basic algebra for manipulating equations
NEXT STEPS
  • Study the ideal gas law and its implications for gas behavior
  • Learn about temperature conversions, specifically between Celsius and Kelvin
  • Explore isochoric and isothermal processes in thermodynamics
  • Investigate real-world applications of gas laws in engineering
USEFUL FOR

Students in thermodynamics, engineers working with gas systems, and anyone interested in the principles of gas behavior under varying pressure and temperature conditions.

A 3.00-L tank contains air at 3.00 atm and 20.0 C. The tank is sealed and cooled until the pressure is 1.00 .
What is the temperature then in degrees Celsius? Assume that the volume of the tank is constant.



P/T=const

3/20=1/T, T=6.67 C

Why it's not right?

nvm, i got it
 
temp should be expressed in kelvin units not "C"
