When the relative humidity is cited as 50 percent, that means that the air is halfway to its saturation point, and that net evaporation is occurring. The dew point is the temperature to which the air needs to cool down to in order to become completely saturated, or reach percent relative humidity. Once the air temperature cools below its dew point, water vapor in the atmosphere will condense.
This causes the relative humidity to go up and down like a roller coaster during the day. The relative humidity will go up at night when the air temperature approaches the dew point, and the relative humidity will go down as the air temperature warms farther and farther away from the dew point during the day. How is vsepr used to classify molecules?
What are the units used for the ideal gas law? How does Charle's law relate to breathing? What is the ideal gas law constant? How do you calculate the ideal gas law constant? How do you find density in the ideal gas law? Does ideal gas law apply to liquids? The dew point is the temperature at which air is saturated with water vapor, which is the gaseous state of water. When air has reached the dew-point temperature at a particular pressure, the water vapor in the air is in equilibrium with liquid water, meaning water vapor is condensing at the same rate at which liquid water is evaporating.
Below the dew point, liquid water will begin to condense on solid surfaces such as blades of grass or around solid particles in the atmosphere such as dust or salt , forming clouds or fog. Dew point is closely linked to relative humidity , which is the ratio of the pressure of water vapor in a parcel of air relative to the saturation pressure of water vapor in that same parcel of air at a specific temperature.
