20% 10/17/17 This is a Numeric Entry question/ It is worth 1 point/You have unlimited attempts/ There is no attempt penalty a See page 275 04 Question point) The severity of a tropical storm is related to the depressed atmospheric pressure at its center. Shown below is a photograph of Typhoon Odessa taken from the space shuttle Discovery in August 1985, when the maximum winds of the storm were about 90 mi/hr and the pressure was 40.0 mbar lower at the center than normal atmospheric pressure. In contrast, the central pressure of Hurricane Andrew was 90.0 mbar lower than its surroundings when it hilt south Florida with winds as high as 165 mi/hr 3rd attempt OF 12 QUESTIONS COMPLETED + VIEW SOLUTION SUBMIT ANSWExplanation / Answer
You need to assume that the temperature of the balloon remains constant in the Typhoon Odessa from its edge till its center so that we can make use of Boyle's law to calculate the volume of the balloon at its new pressure at the center of the Typhoon.
As per Boyle's Law
P1V1 = P2V2
Here
P1 = 1 atm & V1 = 42 L Also,
P2 = 1 atm - 40 mbar
= 1 atm - 0.0395 atm (1mbar = 0.000987 atm, therefore, 40mbar = 0.0395 atm)
= 0.9605 atm
(1atm).(42 L) = (0.9605 atm).V2
V2 = 43.73 L
