Explore atmospheric moisture in this comprehensive Earth Science lecture. Delve into water's changes of state, including solid phase and latent heat. Examine the phase change diagram of water, understanding processes like evaporation, condensation, sublimation, and deposition. Investigate humidity concepts such as saturation, mixing ratio, and relative humidity, and their relationship with temperature. Learn about dew point temperature and methods for measuring humidity. Analyze scenarios involving phase changes, saturation levels, and relative humidity calculations. Gain insights into the temperature at which air parcels reach saturation, enhancing your understanding of atmospheric processes and water cycle dynamics.

HOW IS HUMIDITY MEASURED?
More molecules are returning to the liquid state than are leaving the liquid state. This process is called
As a solid undergoes a phase change to a liquid, it
Which of the following processes absorbs or releases the most heat?
At 25°C it takes 20 grams of water vapor to saturate 1 kilogram of dry air. If there are 5 grams of water vapor in 1 km of air at that temperature, what is the relative humidity?
The temperature at which a dry parcel of air reaches saturation is known as the
