Actividad 1 1. Una propiedad muy importante para identificar sustancias son los distintos puntos en los que se verifican
los cambios de estado. Esta es una propiedad intensiva numérica y, por lo tanto, característica de cada
sustancia
La temperatura a la que una sustancia cambia de estado liquido a estado gaseoso se llama punto de ebullición (PE). Así el PE
del agua es de 100°C (cuando hierve el agua y se hace va-por)del alcohol, 78°C, del mercurio, 357°C, de la glicerina, 290°Cy
de la acetona, 56°C
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°Cde la glicerina, 20°C; y de la acetona, -95°C.
a. Ordenen de menor a mayor los PE y los PF de las sustancias mencionadas.
b. Para cada sustancia, ¿Cuál es la diferencia de temperatura entre el PE y el PF? ayudaaa​
