1A) Calculate the pseudoadiabatic lapse rate for clouds undergoing entrainment when the pressure is 70.0 kPa. The temperature inside the cloud is is 273K, the relative humidity of the environment is 67%. and the initial cloud mass is 100kg. Calculate the lapse rate for the following entrainment rates given the temperature outside the cloud is 272K.

10 kg/km

25 kg/km

50 kg/km

100 kg/km

1B) Calculate the pseudoadiabatic lapse rate without entrainment for this cloud mass.

1C) From a and b, how does entrainment affect the lapse rate inside of a cloud?
