Consider an insulating crystal, made up of layers of atoms. what form would you expect the temperature dependence of the phonon heat capacity to approach at extremely low temperatures if the interlayer coupling is i)very strong (rigid coupling), and ii) very weak. explain.

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
