A relative humidity of 100 percent means that the air is saturated with water vapor. If the environmental lapse rate (ELR) is greater than the moist adiabatic lapse rate (MALR), then the air is conditionally unstable. In this case, the ELR is given as 8 degrees C per kilometer, which is greater than the MALR of around 6 degrees C per kilometer. Therefore, the air is conditionally unstable.
