Melting point of ice decreases with increase in pressure

  • #1
Can someone please explain why the melting point of ice decreases with increase in pressure?
I understand that generally speaking for a solid, greater the pressure applied, greater energy needed to break the bonds to change state and hence greater the temperature (melting point). What is the case with ice?

Ice expands at it freezes and contracts as it melts. So with increased pressure it is energetically more favorable to melt than to freeze. In order to remain at the melting point, temperature must decrease to compensate for increased pressure.
