Ideal Gas Equation and Temperature change?

Click For Summary

Discussion Overview

The discussion revolves around a thermodynamic problem involving the ideal gas equation and the relationship between pressure, volume, and temperature changes in an ideal gas. Participants explore how to calculate the temperature increase of the gas based on given state variables.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant presents a thermodynamic scenario with specific changes in pressure, volume, and temperature of an ideal gas.
  • Another participant questions whether the problem is a homework question.
  • A participant clarifies that it is an old lecture question that remains unclear to them.
  • There is a suggestion to use the ideal gas law relationship, PV/T = constant, to approach the problem.
  • A participant emphasizes the importance of converting temperatures from Celsius to Kelvin before applying the gas law.
  • One participant expresses concern that the problem resembles homework quality and suggests it should be handled in a different context.

Areas of Agreement / Disagreement

Participants do not reach a consensus on how to proceed with the problem, and there is disagreement regarding the appropriateness of discussing it in the current forum context.

Contextual Notes

There is an implicit assumption that temperature must be converted to Kelvin for the ideal gas law to be applied correctly. The discussion does not resolve the mathematical steps needed to arrive at the given answer.

During a thermodynamic process, the state variables of an ideal gas, measured in kPa, m3, and oC, varied in the following way:

P2 = 2P1

V2 = 3V1

T2 = 8T1

What is the temperature increase of the gas, T2 −T1 ?

I've been given an answer of 4780 and I'm not sure how to get there?

Is this a homework problem?
 
No it was an old question in an lecture that I still don't understand
 
Did you try just using the fact that PV/T is constant?
 
Yes but I still can't get the answer that was given
 
Well, according to you, the temperatures are given in celsius. Did you first convert them to Kelvin before using PV/T = constant?
 
Even if it should not be actual homework, it is of homework quality and should be handled there, the usage of our template included.
