Complete Question
A marine biologist is preparing a deep-sea submersible for a dive. The sub stores breathing air under high pressure in a spherical air tank that measures 74.0 wide. The biologist estimates she will need 2600 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. Round your answer to significant digits.
Answer:
The pressure required is
Explanation:
Generally the volume of a sphere is mathematically denoted as
Substituting
Converting to Liters
Assume that the pressure at which the air is given to the diver is 1 atm when the air was occupying a volume of 2600L

Answer:
Vrms is 149.7266 m/sec
Explanation:
The root means square velocity of a gas can be calculated as follows:
Vrms =
where:
R is the ideal gas constant = 8.3145
T is absolute temperature = -55 + 273 = 118 degrees kelvin
M is the molar mass of the gas = 131.293 grams = 0.131293 kg
Substituting with these givens in the above equation, we would find that the Vrms is 149.7266 m/sec
