Question

g The elevation at the trailhead where you start your climb is 3,000 ft. If the outside air temperature at the trailhead at 3,000 ft. is 72ºF. You also find the weather conditions average in terms of normal lapse rate in the troposphere. Given these conditions, what would air temperature be (in º F) at the summit (elevation 7,000 ft) at the same time of your 72ºF reading at the trailhead?

Answer 1

The right answer is "50.48°F".

Step-by-step explanation:

The given values are:

Temperature at 3000 feet,

= 72°F

Temperature change for 1000 feet,

= 5.38°F

Normal lapse rate,

=
`(5.38^(\circ)F)/(1000 \ feet)`

Change in elevation will be:

=
`7000-3000`

=
`4000 \ feet`

hence,

The temperature change for 4000 feet will be:

=
`5.38* 4`

=
`21.52^(\circ)F`

The temperature change for 7000 feet will be:

=
`72-21.52`

=
`50.48^(\circ)F`
