The temperature of a dry air parcel is $20^{\circ} \mathrm{C}$ at a height of $150$ $\mathrm{m}$ with atmospheric pressure of $1000$ $\mathrm{hPa}$. If the air parcel rises adiabatically to a height of $2$ $\mathrm{km}$ where atmospheric pressure is $800$ $\mathrm{hPa}$, then the temperature (in ${ }^{\circ} \mathrm{C}$ ) of the air parcel at that height will be $\_\_\_\_$. (rounded off to three decimal places)
[Gas constant and specific heat capacity for the dry air are $287 \mathrm{~J} \mathrm{~kg}^{-1} \mathrm{~K}^{-1}$ and $1004 \mathrm{~J} \mathrm{~kg}^{-1} \mathrm{~K}^{-1}$, respectively.]
