MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The rate of change of atmospheric pressure P with respect to altitude h is proportional to P, provided that the temperature is constant. At a specific temperature the pressure is 102.5 kPa at sea level and 88.2 kPa at h = 1,000 m. (Round your answers to one decimal place.) (a) What is the pressure (in kPa) at an altitude of 4,000 m? kPa (b) What is the pressure (in kPa) at the top of a mountain that is 6,553 m high? kPa Need Help? Read It Watch It
