Is the entropy change of the ideal gas equals zero?

Click For Summary
SUMMARY

The entropy change of an ideal gas is not equal to zero under typical conditions. Instead, it is calculated using the formula ΔS = Q/T, where Q represents the heat transfer and T is the absolute temperature in Kelvin. In this discussion, Q is specified as 200 kJ and T is calculated as 313 K (40 + 273). Therefore, the entropy change can be determined by substituting these values into the equation.

PREREQUISITES
  • Understanding of thermodynamics principles
  • Familiarity with the concept of entropy
  • Knowledge of the ideal gas law
  • Basic proficiency in unit conversions (e.g., Celsius to Kelvin)
NEXT STEPS
  • Study the laws of thermodynamics
  • Learn about the ideal gas law and its applications
  • Explore the calculation of entropy changes in various thermodynamic processes
  • Investigate the implications of entropy in real-world systems
USEFUL FOR

Students studying thermodynamics, educators teaching physics concepts, and anyone interested in understanding the behavior of ideal gases and entropy changes.

Hi all!
I'm a bit puzzled about this question.
Is the entropy change of the ideal gas equals zero?
And for the second part, is it equal to "Q/T" where Q=200kJ and T=40+273?
I'm not sure about how to handle it...please help.

Please kindly help
 
Sorry mate, I failed thermo last semester. :D
Passing it this year though!

It does seem like this forum has too many novices for the experts to handle.
 
I've moved this thread to the college homework zone.
