Final answer:
Isoflurane is a liquid when sealed but vaporizes in an open container. It has a sweet, fruity scent and is less flammable than diethyl ether.
Step-by-step explanation:
The inhalant anesthetic isoflurane is a liquid at room temperature when stored in a sealed container. However, it vaporizes and becomes a gas when exposed to room temperature in an open container.
It is not odorless, and it has a characteristic sweet, fruity scent.
Regarding flammability, isoflurane is less flammable than the older anesthetic compound diethyl ether.
