A mountain climber climbs to the summit of a 7 km mountain and then returns to his campsite located at the base of the mountain. Explain what happens to the temperature and pressure as he ascends to the summit and returns to his campsite.

The temperature and pressure decreases as he ascends the mountain and increases as he descends the mountain.

We know that temperature and pressure decreases with altitude. In fact, the temperature decreases by 6.5°C for every 1000 meters increase in altitude. Hence air pressure decreases with increasing altitude.

Hence, for a mountain climber, the temperature and pressure decreases as he ascends the mountain and increases as he descends the mountain.

Temperature reduces and pressure increases as he ascends to the summit while the reverse of this happens when he returns to his campsite

Explanation:

When a person climbs a summit, the pressure increases but the temperature reduces. but as he returns to his campsite the normal temperature and pressure are regained which means the pressure reduces and the temperature increase.
