Adiabatic lapse rate never changes. It is not a useful indicator of
stability. It tells you nothing about stability until you know the
actual lapse rate of the air mass in question.

It depends on which adiabatic lapse rate is being considered. The dry
adiabatic lapse rate is basically constant, but the moist/wet rates are not.

Not true as far as I know, but irrelevant nevertheless.

You need to do some research then and learn.


Adiabatic lapse rates, by themselves, tell nothing about stability.
It's the air mass that is either stable or unstable, and one needs to
know what the actual lapse rate of the air mass is in order to
predict stbility or instability.

The "actual" lapse rate is an adiabatic lapse rate. The lifted index is
determined by raising a parcel of air adiabatically.
