Question

The temperature of the air is 26 ∘C at sea level, use the average lapse rate to calculate the expected temperature at the top of a 6000-meter mountain.

Answer 1

-13° C

Step-by-step explanation:

Data provided:

The temperature of the air at sea level = 26° C

The height at which temperature is to be calculated = 6000 m = 6 Km

Now,

Using the average lapse rate

`T_(s+h)=T_s-L_Ph`

Here,

`T_(s+h)` is the temperature at the height 'h' above the mean sea level

`T_s` is the temperature at the mean sea level

`L_P` is the average lapse rate = 6.5° C per Km

h is the height above mean sea level at which the temperature is to be calculated in Km

on susbtituting the respective values in the above formula, we get

`T_(s+h)` = 26° C - ( 6.5 × 6 )

or

`T_(s+h)` = 26° C - 39° C

or

`T_(s+h)` = -13° C
