Expert Answer:

A vapor condenses very readily to the liquid state under small changes of temperature or pressure or both, and constantly does so under ordinary conditions in nature. It may be said to be very close to the liquid state, although it is a vapor. A gas, on the other hand,exists under ordinary conditions in the gaseous state. To change it to the liquid state, special laboratory apparatus with extreme changes of pressure and temperature is required. A gas may be said to be far removed from the liquid state, and cannot change to it under ordinary natural conditions
