For a mixture, the initial melting point is close to the melting point of the lightest compound in the mixture, while the initial freezing point is close to the freezing point (or melting point) of the heaviest compound in the mixture. Since the melting point increases with molecular weight,...
Clausius equation. Melting point of a abnormal substance, such as water, bismuth and gallium, is lowered as the applied pressure is increased. Melting point of normal substance increases as the applied pressure is increased. Table 1 shows dP/dT values for the melting curves of various substances...
