Final answer:
Volatile materials are substances with low boiling points and high vapor pressures. They evaporate readily and do not necessarily have strong odors or toxicity.
Step-by-step explanation:
Volatile materials are substances that have low boiling points and relatively weak intermolecular interactions. They tend to evaporate readily and have high vapor pressures. Examples of volatile materials include diethyl ether, acetone, and gasoline. It is important to note that not all volatile materials are toxic and they do not necessarily have strong, nasty odors.
