Calculate the temperature and relative humidity changes that take place in air as the result of adiabatic cooling.

The subject is natural environments the atmosphere

Atmospheric Moisture
Lab Objectives:
• Explain the processes involved when water changes state.
• Use a psychrometer or hygrometer and appropriate tables to determine the relative humidity and dew-point temperature of the air.
• Explain the adiabatic process and its effect on cooling and warming the air
• Calculate the temperature and relative humidity changes that take place in air as the result of adiabatic cooling.
• Describe the global patterns of precipitation and its variability.
