Question
![**Thermodynamics: Calculating Work Done by an Expanding Gas**
**Problem Statement:**
Consider an ideal gas enclosed in a 1.00 L container at an internal pressure of 24.0 atm. Calculate the work, \( w \), if the gas expands against a constant external pressure of 1.00 atm to a final volume of 24.0 L.
**Single-Step Expansion:**
- Formula for work done by gas:
\[ w = -P_{\text{ext}} \Delta V \]
- Initial Calculation:
\( w = -810.64 \) J
- Note: The calculated value is marked as incorrect.
**Two-Step Expansion Process:**
1. **First Step:**
- Let the gas expand against a constant external pressure of 1.50 atm to a volume of 16.0 L.
2. **Second Step:**
- From the endpoint of step 1, let the gas expand to 24.0 L against a constant external pressure of 1.00 atm.
- Final Calculation for Two-Step Process:
\( w = 3090.565 \) J
- Note: This calculated value is also marked as incorrect.
**Summary:**
This exercise involves calculating the work done by an ideal gas when expanding. The setup involves both a single-step and a two-step expansion process to illustrate different methods of calculation; however, both attempts resulted in incorrect calculations. Further analysis and calculation adjustments are needed for accurate results.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1cab08ae-8e5c-4fa2-a89b-725536e38ab3%2Fbe3fa48b-041c-4c72-a9d5-0a98571af3b7%2Fl6i25nc_processed.png&w=3840&q=75)
