McKee problem # 2
February 28, 2011
The key thing to notice is that the wind from the chinook is fast so it does not
exchange heat with its surrounding. This means that the process is adiabatic [5 pts.].
Also, we are told that the air molecules are diatom

We want to nd the lengths of the two rods given the initial lengths, a change in temperature, and their
coecients of linear expansion. To do this, we use the formula l = l0 T , so that the nal length is given
by lf = l0 (1 + T ).
