WebFluorine is a pale yellow gas that reacts with most substances. The free element melts at −220 °C and boils at −188 °C. Finely divided metals burn in fluorine with a bright flame. Nineteen grams of fluorine will react with 1.0 gram of hydrogen. Classify each of the following changes as physical or chemical: (a) condensation of steam WebMelting and boiling points are affected by the forces between molecules. The larger the attractive forces between the molecules, the more energy needed to overcome them so that molecules can move past each other freely or evaporate (melt or evaporate).
