SUMMARY
The discussion focuses on calculating heat transfer for a gas mass of 0.115 kg that expands from 0.25 m³ to 0.56 m³ at an initial temperature of 32°C and pressure of 1.2 bar. The relevant equations include the work done during expansion, expressed as W = P1V1 ln(V2/V1), and the heat transfer equation Q = U2 - U1 + W. The user successfully solved the problem after initial attempts, demonstrating the application of thermodynamic principles in isothermal processes.
