Answer 2

Calculating Pressure at 800 Meters Altitude

To calculate the pressure at a specific altitude, we can use the barometric formula, which describes how pressure changes with altitude in Earth's atmosphere.

The barometric formula is given by:

P = P0 * (1 - (L * h) / T0)^((g * M) / (R * L))

Where: - P = pressure at altitude - P0 = pressure at sea level - L = temperature lapse rate - h = altitude - T0 = standard temperature at sea level - g = acceleration due to gravity - M = molar mass of Earth's air - R = universal gas constant

Let's calculate the pressure at 800 meters altitude using the given sea level pressure of 760 mmHg.

First, we need to find the standard pressure at sea level and the temperature lapse rate.

Finding Standard Pressure and Temperature Lapse Rate

The standard pressure at sea level is approximately 1013.25 hPa or 760 mmHg [[1]].

The temperature lapse rate, which describes how temperature changes with altitude, is typically around 6.5 °C per 1000 meters in the troposphere [[2]].

Calculating Pressure at 800 Meters Altitude

Using the barometric formula and the given values: - P0 = 760 mmHg - L = 6.5 °C per 1000 meters - h = 800 meters - T0 = standard temperature at sea level (assumed to be 15 °C) - g = 9.81 m/s^2 - M = 0.029 kg/mol (molar mass of dry air) - R = 8.314 J/(mol·K) (universal gas constant)

We can calculate the pressure at 800 meters altitude using the barometric formula.

Let's proceed with the calculation.
