\section{Objective}
Evaluate model accuracy for transient heat response under controlled boundary conditions.

\section{Setup}
A metal rod is instrumented with four thermocouples at equal distances. Heating is applied at one boundary for 120 seconds, followed by passive cooling.

\section{Procedure}
\begin{enumerate}
  \item Calibrate sensors and record baseline.
  \item Apply heat source at constant power.
  \item Capture readings at 1-second resolution.
  \item Repeat three runs and average.
\end{enumerate}

\section{Observations}

\toprule
Probe & Peak (\(^{\circ}\)C) & Time to peak (s) \\
\midrule
P1 & 79.2 & 34 \\
P2 & 68.5 & 51 \\
P3 & 58.7 & 74 \\
P4 & 49.9 & 93 \\

\end{table}

\section{Error Analysis}
Major uncertainty sources include sensor contact quality and ambient airflow fluctuations. Combined uncertainty is estimated at \(\pm 1.4^{\circ}\)C.

\section{Conclusion}
The measured propagation profile agrees with the theoretical diffusion trend, with largest residuals near boundary transitions.
