If there is no cloud (liquid water) in the parcel, the air temperature in the parcel increases at a rate of 10°C for every 1000 meters the parcel is lowered. If there is a cloud in the parcel, it will evaporate because as the parcel warms its capacity for water vapor increases.
Different materials will change temperature at different rates when exposed to the same amount of heat. This is because the different materials absorb heat at different rates.
