The density of water vapor can vary depending on temperature and pressure. At standard temperature and pressure (STP), the density of water vapor is approximately 0.804 grams per liter (g/L). However, as temperature increases or pressure decreases, the density of water vapor decreases.
Temperature
I would have to say water vapor. Since a desert is very dry with little rain which means no water vapor while a rain forest obviously gets lots of rain. It's also very hot and humid which means lots of water vapor.
ANSWER:Because. That's why. That's my first choice because my second choice is a little longer. Clouds are collections of water vapor, not water. The difference is similar to when you exhale in the cold air, the humidity in your breath can be seen but it is not water. It can make a mirror fog up but cannot fill a glass with liquid. Theres not enough volume because its just vapor. This vapor, when in a large enough quanty can create clouds in the sky. As the humidity level gets higher, there is more water vapor in the air and this can leave little droplets on your windshield. The more dense the vapor becomes, mist and rain develops. The more vapor contained in a cloud allows less light through making it dark on the bottom into what we call a rain cloud.
The word "vapour" is in the King James Version of the Bible 5 times. It is in 5 verses.
The sample with the highest vapor pressure will be the one with the highest temperature listed in Reference Table H. Generally, higher temperatures result in higher vapor pressures for a substance.
Nearly all of the Earth's atmosphere is made up of only five gases: nitrogen, oxygen, water vapor, argon, and carbon dioxide. Several other compounds also are present. Although this CRC table does not list water vapor, air can contain as much as 5% water vapor, more commonly ranging from 1-3%. The 1-5% range places water vapor as the third most common gas.
The typical Reid vapor pressure range in naphtha is between 2 to 15 pounds per square inch (psi). Reid vapor pressure is a measure of the vapor pressure of volatile petroleum products, including naphtha. High Reid vapor pressure indicates increased volatility.
The vapor pressure of propanone (acetone) at 45 degrees Celsius is approximately 365 mmHg according to reference table h.
Water vapor falls into that range depending on weather conditions.
At 117°C, the vapor pressure of water is approximately 2566 Pa.

Use the Equation of State (EOS) in combination with the Antoine's Equation to determine vapor pressure.
The FR (flammable range) of gasoline is 1.4% LEL (lower exposive limit) to 7.6 UEL (upper exposive limit). Below 1.4% the gasoline vapor is said to be too lean and above 7.6% and the vapor is too rich. In either case gasoline will not burn if it is not in the FR.
The vapor pressure of water at 72 degrees Celsius is approximately 28.1 mmHg.
It ranges from almost none up to almost 4% in some tropical regions.
The vapor pressure of ethanol at 14 degrees Celsius is approximately 63.1 mmHg.
