  1. The 3 most important changes through which moisture changes can occur are ???
    Condensation,

    Evaporation,

    • Precipitation
    •  
  2. When water evaporates, it (adds to/subtracts from?) partial vapour pressure of air, and thereby it (increases/decreases?) atmospheric pressure?
    Adds to,

    Increases 
  3. The saturation vapour pressure of moist air is determined by the airs (?) in that a higher (?) will produce a (higher/lower?) saturation vapour pressure?
    Temp,

    Temp,

    Higher. 
  4. Does the demand for or release of Latent energy effect the temp of the substance undergoing the change?
    Nope
  5. The four main factors that affect the the rate of evaporation are what?
    • Temp,
    • Water content of air,
    • Wind,
    • Air pressure. 
  6. When water vapour changes to Ice, the process is called ? and does it demand or release latent energy?
    Depostion and it releases latent energy.
  7. Humidity mixing ratio is the percentage expression of the mass of (?) in gramms per (kilo/litre?) of (moist/dry?) air
    Water Vapour,

    Per kilo of dry air. 
  8. Absolute humidity means the (weight/pressure) of water vapour per unit (mass/volume?) expressed as ? per ?
    weight or mass

    volume,

    Grammes per m3
  9. List three methods by which relative humidity can be measured?
    Wet Bulb/Dry Bulb,

    Hair Hygrometer,

    Lithium Chloride Element. 
  10. When moisture is added to the atmosphere, The density of Air (increases/decreases?)
    Decreases.
