WebHeat keeps flowing until the objects reach the same temperature (equilibrium). Heat transfers faster between objects with greater temperature differences. Likewise, larger areas of contact (surface area) and longer times (duration) of contact lead to faster heat transfer. The type of materials involved also affect the rate of heat transfer Web16 jul. 2024 · Heat conduction is the transfer of heat between two objects in direct contact with each other. The rate of heat transfer Q / t (energy per unit time) is proportional to the temperature difference T2 − T1 and the contact area A and inversely proportional to the distance between the objects: Q t = kA(T2 − T1) d.
