Measurement of the convective heat-transfer coefficient [PDF]
Phys. Teach. 52 (2014) 109, 2014 We propose an experiment for investigating how objects cool down toward the thermal equilibrium with its surrounding through convection. We describe the time dependence of the temperature difference of the cooling object and the environment with an exponential decay function.
