Question

Air Temperature As dry air moves upward, it expands and,
in so doing, cools at a rate of about 1°C for each
100-meter rise, up to about 12 km.
(a) If the ground temperature is 20°C, write a formula for
the temperature at height h.
(b) What range of temperatures can be expected if an airplane takes off and reaches a maximum height of 5 km?
