: [ W = nRT \ln\left(\frac{V_f}{V_i}\right) ] or for an ideal gas in an isothermal process, [ W = P_1V_1 \ln\left(\frac{V_f}{V_i}\right) ] Given (P_1V_1 = P_2V_2) for an ideal gas, [ W = 100 \times 20 \ln(2) = 2000 \ln(2) , \text{J} \approx 1385.7 , \text{J} ]
This example illustrates a straightforward application of thermodynamic principles to solve a problem. For more complex problems, break them down step by step and ensure you understand the underlying thermodynamic principles. : [ W = nRT \ln\left(\frac{V_f}{V_i}\right) ] or
