Final answer:
Nonmetals have the property of evaporating easily due to weak intermolecular forces and low boiling points.
Step-by-step explanation:
Nonmetals have a property of evaporating easily, which is called volatility. Volatility refers to the tendency of a substance to vaporize or evaporate at a low temperature. Nonmetals, such as hydrogen, oxygen, nitrogen, and chlorine, are often volatile due to their weak intermolecular forces and low boiling points.
For example, chlorine gas (Cl2) is a nonmetal that easily evaporates at room temperature and forms a greenish gas. This is because the chlorine molecules have weak intermolecular forces and can escape from the liquid phase into the gas phase.
