Question

Molecules that are of density row=180 kg/m3 and spe- cific heat cp = 3000 J/kg * K have an initial, relaxed length of L=2nm. The intensity of the molecular vibration increases exponentially from an initial value of Ii to a steady-state value of Iss > Ii with the time constant associated with the exponential response being pi I = 5 ps. Assuming the intensity of the molecular vibration represents temperature on the molecular scale and that each molecule can be viewed as a cylinder of initial length L and cross-sectional area Ac, determine the thermal contact resistance R"tc at the metal-moleculte interface.

Explanation / Answer

use q=m c T
