2 3 4 A marine biologist is preparing a deep-sea submersible for a dive. The sub stores breathing air under high pressure ina spherical air tank that measures 88.0 cm wide. e biologist estimates she will need 4700. L of air for the dive. Calculate the pressure to which this volume of air must be compressed in order to fit into the air tank. Write your answer in atmospheres. Be sure your answer has the correct number of significant digits. atm d image text Answer nymous answered th 79 answers persion forces >p y small charge inter choose ALL disperi npolar species Submit Assignm Worked Example

Explanation / Answer

She needs 4700L air at atmospheric pressure

As the temperature of cylinder has to be same as atmospheric temperature ,T essentially remains constant

P1V1 = P2V2

V2 = 1/6 x pi x (0.88m)3 = 0.356637 m3 = 356.637 L

1 atm x 4700L = P2 x 356.637L

P2 = 13.17866 atm = 13.2 atm with significant digits = 1.32 x 101
