Q: If the atmospheric pressure at sea level is 1013 hPa, what is the pressure at 5000 meters altitude approximately?

Solution: The atmospheric pressure at 5000 meters is approximately 700 hPa.

Steps: 7

Step 1: Understand that atmospheric pressure decreases as altitude increases.
Step 2: Know that at sea level, the atmospheric pressure is 1013 hPa.
Step 3: Recognize that at 5000 meters, the pressure is significantly lower than at sea level.
Step 4: Use a rough estimate that atmospheric pressure decreases by about 12 hPa for every 100 meters of altitude.
Step 5: Calculate the total decrease in pressure from sea level to 5000 meters: 5000 meters / 100 meters = 50. This means the pressure decreases by approximately 50 * 12 hPa = 600 hPa.
Step 6: Subtract this decrease from the sea level pressure: 1013 hPa - 600 hPa = 413 hPa.
Step 7: However, a more accurate approximation for 5000 meters is around 700 hPa, which is a commonly accepted value.
