An ideal gas undergoes a cyclic process \(A \rightarrow B \rightarrow C \rightarrow A\) as shown in the \(P\text{--}V\) diagram. Step \(A \rightarrow B\) is a linear expansion from state \(A\, (1.0 \times 10^{-3} \text{ m}^3, 1.0 \times 10^5 \text{ Pa})\) to state \(B\, (4.0 \times 10^{-3} \text{ m}^3, 3.0 \times 10^5 \text{ Pa})\), step \(B \rightarrow C\) is an isochoric pressure reduction, and step \(C \rightarrow A\) is an isobaric compression back to state \(A\). What is the net thermal energy transferred to the gas during one complete cycle?
