Answer:
The reason is because both are exposed to a virtually infinite heat sink, due to the virtually infinite mass and of the surrounding environment, compared to the sizes of either the cup or the kettle such that the equilibrium temperature,
reached is the same for both the cup and the kettle as given by the relation;
![\infty M_{(environ)} \times c_{(environ)} \times (T_2 - T_1) = m_{1} \times c_{(water)} \times (T_3 - T_2) + m_{2} \times c_{(water)} \times (T_4 - T_2)](https://tex.z-dn.net/?f=%5Cinfty%20M_%7B%28environ%29%7D%20%5Ctimes%20%20c_%7B%28environ%29%7D%20%5Ctimes%20%28T_2%20-%20T_1%29%20%3D%20m_%7B1%7D%20%5Ctimes%20%20c_%7B%28water%29%7D%20%5Ctimes%20%28T_3%20-%20T_2%29%20%2B%20m_%7B2%7D%20%5Ctimes%20%20c_%7B%28water%29%7D%20%5Ctimes%20%28T_4%20-%20T_2%29)
Due to the large heat sink, T₂ - T₁ ≈ 0 such that the temperature of the kettle and that of the cup will both cool to the temperature of the environment
Explanation:
The resistance of a wire is directly proportional to the length of the wire. That is the longer the length of the wire, the higher the resistance and the shorter the length of the wire, the smaller the resistance.
