Humidity Flashcards
What are essential for starting binding process - vapour to liquid droplets
Condensation nuclei
What combines to form larger water droplets?
Microscopic water particles.
What is deposition?
Changing from gas to solid (or solid to gas) – bypassing the liquid stage (sometimes referred to as deposition).
Provide 2 examples of nuclei
For condensation to occur, nuclei must be present such as: salt, dust, aeroplane.
When air contains the maximum amount of water vapour that it can hold it is _________
saturated
Temperature influences the amount of energy available to keep the vapour molecules from combining to create liquid.
Warmer the air, more energy, therefore able to accept more water vapour from the surroundings.
The total amount of water vapour present in a given volume is measured in?
grams per meter cubed (m³)
Water Vapour Pressure (WVP) is similar to ________ ________.
Absolute humidity is similar to Water Vapour Pressure (WVP) – pressure each water vapour molecule exerts
The ratio of the mass of water vapour in a given volume of air (absolute) to the maximum mass of water vapour (for the same temperature).
Describes?
Relative Humidity (RH).
Relative humidity equation?
𝑹𝑯 %=𝟏𝟎𝟎 −(𝟓 𝑿 (𝑻−𝑻𝑫))
T = ambient temperature
TD = dew point
