Homework Statement
Derive an expression for the change in temperature with pressure for an adiabatic process. If a dry air parcel is lifted adiabatically from 1000hPa to 800hPa what is the final temperature if it was initally at 20[itex]^{o}[/itex]C?[itex]^{}[/itex]
Homework Equations
[itex]PV^{k}=constant[/itex]
I derived an equation [itex]\frac{T_{2}}{T_{1}}= \frac{P_{2}}{P_{1}}^{\frac{k-1}{k}}[/itex]
Not sure if this is the correct equation?
The Attempt at a Solution
[itex]k = \frac{c_{p}}{c_{v}}[/itex]
I'm not sure if this is even the right direction for this question, and if it is where can I get the value of the c's?
Any help would be appreciated. thanks =D
