1. The problem statement, all variables and given/known data When ice at 0 degrees is placed into an environment that is colder than it, the ice will transfer heat to it's environment. However, if one layer of ice (meaning 2 molecules of H2O thin) is heated with just enough heat energy to melt it, will heat still be conducted? 2. Relevant equations none 3. The attempt at a solution I'm quite confused because when the heat is absorbed the water molecules vibrate more so they become further apart. However, as they vibrate more won't the neighboring water molecules also get pushed around and vibrate as a result. So by the conservation of energy the exact amount to free 2 molecules by allow that one molecule to vibrate so intensely isn't enough due to some energy loss to the second layer?
