Enthalpy Changes During Phase Transitions

Posted on July 5, 2017 by Mrs Shilpi Nagpal

Hess's Law

Enthalpy of fusion Enthalpy of fusion is the enthalpy change accompanying the transformation of one mole of a solid substance into its liquid state at its melting point. it is also called molar enthalpy of fusion. The molar enthalpy of fusion ( Δ fus H ) of ice is +6 KJ mol-1. H2O ( s ) -----------> H2O ( l )  Δfus H = + 6 KJ mol-1 The enthalpy of freezing has … [Read more...] about Enthalpy Changes During Phase Transitions
