a$)$ If the atmospheric condition at sea level is $101\mathrm{.}3$kPa and $10C,$ estimate and plot the

pressure as a function of elevation $($for up to $10km$ above sea level$)$ for the following conditions:

i$.$ Air temperature is constant

ii$.$ Air temperature decreases linearly with elevation at a rate of $5\mathrm{.}5\frac{C}{k}m.$

Assume air is an ideal gas
