Question

A sample of an ideal gas at 1.00 atm and a volume of 1.39 L was placed in a weighted balloon and dropped into the ocean. As the sample descended, the water pressure compressed the balloon and reduced its volume. When the pressure had increased to 30.0 atm, what was the volume of the sample? Assume that the temperature was held constant. 𝑉=

Answer 1

For this problem, we need to use the ideal gas law, PV = nRT.

As the temperature is constant, and the gas mass doesn't change,

we can use P1/ P2 = V2/V1 and solve for V2.

V2 = 1.00 atm x 1.39 L / 30.0 atm = 0.0463 L
