As dry air moves upward it expands and in doing so cools at a rate of 1 degrees Celsius for each 100 m rise up to about 12 km

If the ground temperature is 20 degrees Celsius find an expression for the temperature T as a function of the height H

the answer is T=20-10h(h in kilometers) please show and explain steps thanks

nothing to show.

They said T started out at 20 and decreased by 10 for each km.

just subtract 10 for each km, starting from 20.

If that's not clear, make a table for values of h from 0 to 12:

h 0 1 2 3 4 ...

T 20 10 0 -10 ...
