Question

Write a thermochemical equation for the melting of ice (include the energy term)

Answer 1

$H_2O (s) \to H_2O (l) \ \ ( \space \triangle H = 6.00 kJ)$

This means when ice is melted ,an energy of 6 kilo joule is required.

or,the enthalpy of one mole of water is greater than that of ice by an amount of 6 KJ
