The Clausius-Clapeyron equation relates the slope of a two-phase curve to the

  • A.critical temperature of the substance
  • B.latent heat and the volume change of the transition
  • C.number of components and phases present
  • D.specific heats of the two phases

Answer: B

It quantifies what the phase rule only says qualitatively about a univariant curve, giving the gradient in terms of the enthalpy change and the volume change. The negative volume change on melting ice is what makes its fusion curve slope backwards.
