Problem
Explain, without calculation, how the initial rate of temperature increase of a small aluminum sphere attached to the cold end of a copper rod changes if the rod’s length is doubled while all other variables (cross-sectional area, temperature difference between the rod’s ends, mass and specific heat of the sphere) remain the same.
