Question

Braydon, a scuba diver, has a tank that holds 6 liters of air under a pressure of 220 pounds per square inch (psi).

Write the equation that relates pressure, P, to volume, V.


If the pressure increases to 330 psi, how much air is held in Braydon’s tank?

Answer 1

V=1320/p

the tank holds 4 liters

Explanation:

Answer 2

Answer: 4 litres of air is held in Braydon’s tank.

Explanation:

The law relating pressure to volume is the Boyle's law. It states that the volume of a given mass of gas is inversely proportional to its pressure as long as temperature remains constant. It is expressed as

P1V1 = P2V2

Where

P1 and P2 are the initial and final pressures of the gas.

V1 and V2 are the initial and final volumes of the gas.

From the information given,

V1 = 6 litres

P = 220 psi

P2 = 330 psi

Therefore,

6 × 220 = 330V2

V2 = 1320/330 = 4 litres
