1. energy transfer via thermal conduction–cooling heated metal in water, temperature rise correlation, safety during flame heating
2. damping in oscillations–logarithmic decay of amplitude, plotting ln θ vs n, extracting damping constant λ, graphical interpretation
3. density of stacked metal rings–mass and volume calculation using cross-sectional area and total thickness, propagation of uncertainties
4. evaluation of material identity–comparison of measured density range with stainless steel standards to confirm material composition possibility
