- La siguiente tabla, expone cómo desciende la temperatura (T) del aire con la altitud(h): Temperatura (ºC) 15 13,5 12 10,5 9 Altitud (m) 0 250 500 750 1000 Dado que la relación entre altura y temperatura viene dada por la siguiente fórmula: T=k*h+To Representa gráficamente los datos de la tabla y calcula To, que es la temperatura inicial (a una altitud de 0), y el valor de la constante k (pista k<0).
