Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the dew point and why does it matter?The dew point is the temperature at which air becomes saturated and water vapor turns into liquid. When the air cools to this temperature, dew or fog can form.
2. How does the dew point affect how we feel on a hot day?When the dew point is high (above 65°F), the air feels muggy because sweat doesn't evaporate easily. A low dew point (below 55°F) makes the air feel drier and more comfortable.

Saturation Vapor Pressure: The maximum pressure water vapor can exert at a given temperature before condensing.
Dew Point Depression: The difference between the air temperature and the dew point temperature.
Deposition: The phase transition from water vapor directly to ice, without passing through the liquid phase.
