The arrest in cooling during solidification allows the melting point of the material to be identified on a time temperature curve Most systems consisting of two or more components exhibit a temperature range over which the solid and liquid Cooling curves are obtained by plotting the measured temperatures at equal intervals during the cooling period of a melt to a solid The data obtained from these cooling curves are useful in constructing the equilibrium diagram
Heating and cooling curves are graphs They plot a substance s temperature y axis against heat x axis For heating curves we start with a solid and add heat energy For cooling curves we You need to be able to accurately label and sketch a cooling curve graph AND explain it As you cool the substance you are decreasing the internal energy BUT the temperature stays
