Will a change in temperature cause the dew point to change?

Answer 1

By definition, Dewpoint is:

"The Temperature at which the water vapour present in the air saturates the air and begins to condense ie dew begins to form"

(from "A Dictionary of Science" Penguin Books 1964)

To understand "Dewpoint" one must understand Condensation, and to understand "Condensate" one must understand States of Matter and Molecular Energy, and only then can the Question be answered.

Condensation happens when several gas molecules come together and form a liquid. It all happens because of a loss of energy. Gases are really excited atoms. When they lose energy, they slow down and move to a lower-Energy State of Matter, where the molecules get denser or packed closer together. An example of a Condensate is when Water (H2O) vapor in the form of steam loses energycondenses on the lid of the kettle when boiling water, it cools, and becomes a liquid again. You would then have a condensate.

However, there are actually 5 states of Matter, not 3, but 3 are straightforward because the 3 states of Solid [ice], Liquid [water], and Gas [steam] are visible . The other two States of Matter are 'Plasma', and 'Bose-Einstein Condensate' or BEC, and both are invisible and both are total opposites. However, the only difference between all five States of Matter is the Temperature and therefore the amount of Molecular Activity.

Bose-Einstein Condensate or BEC

Two scientists, Satyendra Bose and Albert Einstein, had predicted a 5th state of matter which would occur at very very low temperatures in 1924, but they didn't have the equipment and facilities to make it happen at that time. But now we do: the Bose-Einstein condensate was physically discovered for the first time in 1995 by Wolfgang Ketterle and his team of graduate students, and in 2002, Ketterle and two other scientists received the Nobel Prize for it. It is known for short as the BEC..By definition, at zero degrees Kelvin (Absolute Zero) all molecular motion stops, but scientists have figured out a way to get a temperature only a few billionths of a degree above absolute zero. When temperatures get that low, atoms are super unexcited and super cold, and can no longer bounce around as individuals. Instead they must all act in exactly the same way, and you can no longer tell them apart!. The substance is not just a frozen solid, but is in its 5th state of matter , that of .Bose-Einstein Condensate' or BEC

Solid

When a substance is in the state of BEC and then its atoms begin to bounce around as individuals it is said to be a Solid. They then have Structural rigidity. i.e. they have definite shape and occupy a specific area and volume. When temperatures are increased Solids become the next State of Matter, Liquid.

Liquid :

Liquids lack rigidity in shape, but take the shape of the container which contains them. They occupy a specific volume and generally do not expand to occupy the entire available volume unless the Temperature is heated and they become a Gas.

Gas :

A Gas has no definite shape, and they expand to occupy the entire available volume unlike solids and liquids. Gases are really excited atoms, but when Temperatures are massively increased they become a Plasma.

Plasma :

.A Plasma is a result of rise in temperature causing the Ionization of a gas. This means that Atoms are heated to super-high temperatures between between 1000°C and 1,000,000,000°C. until their nucleus and electrons are detached from one another, at which point they are said to be 'Ionized' and are called a 'Plasma'. Plasma is the ultimate possible result of rise in temperature of anything. Plasmas are super hot and super excited atoms, but the atoms in a Bose-Einstein condensate (BEC) are total opposites: they are super unexcited and super cold atoms.

So, to answer the Question,

the higher the Dewpoint the more Watervapour there is in the Air.

Answer 2

The dew point could remain the same as temperature rises if this last increases its water vapor as temperature increases

ex.

there's a cloud, and a current of warmer, moist air passes through it, it warms the cloud and increases the water vapor, but dew point stays the same because the warmer the air, the more water vapor it can hold

Answer 3

No. Dew point depends on the amount of moisture in the air, and not on temperature. It is relative humidity that depends on both temperature and moisture content.

Answer 4

The question is nonsense

Answer 5

yes

Answer 6

no
