How to Find Work Done by an Ideal Gas with Given Conditions?

Click For Summary
SUMMARY

The discussion focuses on calculating the work done by an ideal gas during a state change at constant pressure with varying volume. The ideal gas in question is quantified as 1 mole, and the gas constant R is specified as J/(mol*K). The formula for work done, W = P(V2 - V1), is highlighted, but the user struggles to derive the necessary values for pressure and volume due to insufficient data. The connection between the gas quantity and the gas constant is also questioned, indicating a need for clarity in applying the ideal gas law.

PREREQUISITES
  • Understanding of the Ideal Gas Law (PV = nRT)
  • Knowledge of thermodynamic concepts related to work done by gases
  • Familiarity with the properties of ideal gases
  • Basic algebra for manipulating equations
NEXT STEPS
  • Learn how to derive volume from the Ideal Gas Law using given temperature and pressure
  • Study the relationship between pressure, volume, and work done in thermodynamics
  • Explore the concept of isobaric processes and their implications for ideal gases
  • Investigate graphical representations of PV diagrams and their interpretations
USEFUL FOR

This discussion is beneficial for students studying thermodynamics, physics enthusiasts, and anyone involved in engineering fields that require an understanding of gas behavior under varying conditions.

For example there is change state on an ideal gas. The temperature of states are X and Y. The change on X and Y is a change of constant pressure but increasing in volume. Let the quantity of the ideal gas be 1[mol], and let R[J/mol*K] denote the gas constant. Find the work which the gas did on the outside during the state change from X to Y.

Note: I have difficulty on the finding the work done using the formula W=PV because there is no amount given for temperature, pressure and volume. And secondly, the formula for Work done on an gas is only Pressure and Volume, what is the connection of the quantity of the ideal gas be 1[mol], and let R[J/mol*K] denote the gas constant?Please help me.

can you get V1 and V2 using PV=mRT etc?? Then W=P(V2-V1)
 
Homer Simpson, I cannot get the value of it since that's the only given. The original graph is located at www.geocities.com/willydavidjr/pvdiagram ...The X and Y I am talking about is the change from state 2 to 3.
