The document outlines 16 experiments related to heat transfer. Experiment 1 examines Fourier's Law of heat conduction along a brass bar. Experiment 2 looks at heat conduction along a composite bar. Experiment 3 analyzes the effect of cross-sectional area changes on temperature profiles. The remaining experiments involve topics like radial heat conduction, thermal conductivity of materials, free/forced convection, extended surfaces, inverse square law, Stefan-Boltzmann law, and various heat exchanger designs. Temperature and heat transfer measurements are recorded for each experiment.
