A 3 L pocket of air at sea level has a pressure of 100 atm. Suppose the air pockets rise in the atmosphere to a certain height and expands to a volume of 10 L. What is the pressure of the air at the new volume?

30 atm

Explanation:

Initial Volume, V1 = 3L

Initial Pressure, P1 = 100 atm

Final Volume V2 = 10 L

Final Pressure, P2 = ?

These quantities are related by the Boyle's law equation which is given as;

V1P1 = V2P2

P2 = V1 * P1  /  V2

P2 = 3 * 100 / 10

P2 = 30 atm

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
