# At the foot of the mountain, the air temperature is 12 degrees Celsius, atmospheric pressure is 768 mm Hg.

At the foot of the mountain, the air temperature is 12 degrees Celsius, atmospheric pressure is 768 mm Hg. Determine the temperature and pressure at the summit if it is known that the height of the mountain is 3500m.

We take the value of the temperature change for every 100 meters as 0.6 degrees Celsius

In this case, the temperature difference will be:

3500/100 * 0.6 = 21 degrees Celsius.

The temperature at the top will be:

12 – 21 = – degrees Celsius.

A change in atmospheric pressure by 1 mm Hg occurs with an increase in height by 10.5 meters.

In this case, the pressure difference will be:

3500 / 10.5 = 333 1/3 mm Hg

The pressure at the top of a mountain 3500 m high will be equal to:

768 – 333 1/3 = 434 2/3 mm Hg
