Question: The temperature of the atmosphere is not always constant and can increase or decrease with height. In a neutral atmosphere, where there is not a significant amount of vertical mixing, the temperature decreases at a rate of approximately 6.5 K per km.

Assume that the surface pressure is p_{0} = 1.013\ \times \ 10^{5}\ \text{Pa} where \text{T} = 293\ \text{K} and the lapse rate is \left( {\text{−}\Gamma = 6.5\frac{\text{K}}{\text{km}}} \right) .
