This material is made available for the sole purpose of studying and learning - misuse is strictly forbidden.1) An adiabatic process is one in which no heat is transferred into or away from the system. Note that this is not an isothermal process. An isothermal process takes place at constant temperature while an adiabatic process is not required to do so.
2) The moist adiabatic rate of cooling is less than the dry adiabatic rate of cooling because moist air rising condenses out its water vapor (once saturation is attained). This condensation releases heat which results in a slower rate than if no condensation took place (cooling dry adiabatically).
3) The two rates become more similar as the air becomes cooler....
