How does mass affect heat transfer

WebThe benefit of thermal mass is shown in this comparison of how heavy and light weight constructions affect internal temperature. In building design, thermal mass is a property of the mass of a building that enables it to store heat and provide inertia against temperature fluctuations. It is sometimes known as the thermal flywheel effect. [1] WebExperiments show that the heat transferred to or from a substance depends on three factors—the change in the substance’s temperature, the mass of the substance, and certain physical properties related to the phase of the substance. The equation for heat transfer Q is Q = m c Δ T, 11.7
