Measurement of the Convective Heat-Transfer Coefficient [PDF]

open access: yesThe Physics Teacher, 2014
We propose an experiment for investigating how objects cool down toward the thermal equilibrium with their surroundings. We describe the time dependence of the temperature difference of the cooling objects and the environment with an exponential decay function.
