    When a parcel of air becomes saturated and condensation occurs -

    latent heat is released

  • 2

    Relative humidity is -

    The percentage degree of saturation

  • 3

    The dew point is the temperature -

    to which a sample of moist air must be cooled at a constant pressure for it to become saturated

  • 4

    When water droplets in the liquid state freeze -

    latent heat is released

  • 5

    Relative humidity is measured using a -

    Psychrometer

  • 6

    A parcel of air has a temperature of +15 degrees and a relative humidity of 80%. A temperature rise of 10 degrees will cause -

    the relative humidity to decrease

  • 7

    The water vapour held in saturated air is -

    invisible always

  • 8

    When the temperature and dew point are the same -

    the relative humidity is 100%

  • 9

    The reading of wet and dry bulb thermometers at meteorological stations serves to calculate -

    humidity

  • 10

    Relative humidity is the -

    ratio of the amount of water vapour present to the amount that could be held in a sample of air

  • 11

    When the air temperature at a particular level is higher than that existing at a lower level

    an inversion exists
