the rate of cooling that occurs when dry air rises without gain or loss of heat
There are two types of adiabatic lapse rates...wet and dry. (wet is also referred to as saturated or moist) To the extent that the cloudiness your question refers to represents saturated air, then no, the wet adiabatic lapse rate would be lower (approximately 1.5C/1000') than the dry adiabatic lapse rate (approximately 3C/1000').

the rate of cooling that occurs when dry air rises without gain or loss of heat
environmental lapse rate involves the actual temperature of the atmosphere at various heights. adiabatic cooling is the cooling of air caused when air is not allowed to expand or compress.
Then the air is called "stable" because a parcel of air from the surface lifted upward will drop in temperature at the dry adiabatic lapse rate. If the environmental lapse rate is less, then the lifted air will be cooler and more dense than the surrounding air, and thus stop moving upward through the atmosphere.
They are called conditionally unstable,
Absolutely Stable Air
Air that is rising at the dry adiabatic rate can simply cool at the rate at which the decreasing pressure forces it to. Once it cools to its dew point at the lifting condensation level, it must condense some of its moisture in order to cool anymore (it is already saturated at this point). Condensation is a process that releases latent heat into the atmosphere, warming the air. Therefore, this heat released counteracts some of the adiabatic cooling that continues to take place as the air rises, and the net effect is a rate of cooling that is reduced. This is the saturated (or moist) adiabatic lapse rate.
