We propose a novel mechanism for Kapitza conductance between phonons in solid and quasiparticles in dilute - liquid mixtures. This conductance is large only when the interface between the liquid and solid is rough. We have measured this conductance using a dynamical method, and have obtained results in agreement with the theory.
