Answer:
Step-by-step explanation:
The rate of breathing is affected by the environment's pressure and temperature. The pressure and temperature are lower at greater altitudes. As a result, the man's lungs will have to work harder to breath the same volume of air. We may use the following calculation to compute the new rate of breathing:
(Pressure1 x Temperature1) x Rate of breathing1 = (Pressure2 x Temperature2) x Rate of breathing1
Where Pressure1, Temperature1, and Rate of breathing1 are the pressure, temperature, and rate of breathing at sea level (760mm Hg, 18 degrees Degrees c, and 16 breaths per minute), and Pressure2, Temperature2 are the pressure and temperature at the mountain top (760mm Hg, 18 degrees Celsius, and 16 breaths per minute) (240mm Hg, 5 degrees C)
Plugging in the values, we get:
Rate of breathing = (760 x 18) / (240 x 5) x 16
Rate of breathing = 4 x 16
Rate of breathing = 64 breaths per minute
So the man's rate of breathing at the mountain top would be 64 breaths per minute. This means that his lungs would have to work 4 times harder to inhale the same mass of air as at sea level due to the lower pressure and temperature at the mountain top.
