El punto de fusión (PF) es la temperatura a la que una sustancia cambia de estado sólido a liquido. Por ejemplo, el PF del agua es de 0°C (cuando se congela el agua y se hace hielo); del alcohol, -117 °C, del
mercurio. -39°C. de la glicerina, 20°C; y de la acetona, -95°C.
Ordenen de menor a mayor los PE y los PF de las sustancias mencionadas
