Determination of enthalpy of melting in a pure substance. P3020911

You can get the concept of:
The melting point and enthalpy of melting, latent heat, phase Gibbs', calorimetry, heat capacity.

Principle:
For melting the substance energy is required for the destruction of the crystal lattice. A substance whose melting point is slightly below room temperature, initially cooled to the solid state, and then melted in the calorimeter. Based on the changes in temperature in the calorimeter is known heat capacity of the system calculated the enthalpy of the melting process.
