When droplets of condensation form on the outside of a glass of ice water,it must be that in the air right next to the glass
A)the temperature is near the dew point.
B)the humidity is near the saturation density.
C)the relative humidity is near 100%.
D)all of the above

Question

Quizplus · Accepted Answer

Droplets of condensation form on the outside of a glass of ice water when the temperature of the glass surface is below the dew point temperature of the air next to it. The dew point temperature is the temperature at which the air would become saturated with water vapor if it were cooled further. Therefore, when the temperature near the glass is near the dew point temperature, it means that the humidity is near the saturation density, and the relative humidity is near 100%. So, all of the choices (A), (B), and (C) are correct.
