A meteorological research team uses a high-pressure cylinder of compressed helium gas to inflate weather balloons, as shown in the diagram below.

Helium Cylinder connected to a Weather Balloon

Each fully inflated weather balloon has a volume of 0.12 m3 at a local atmospheric pressure of 101 kPa.

The supplier of the cylinder claims that you can inflate at least 17 weather balloons using the gas from a single cylinder.

Comment on the supplier's claim.

Use information about the pressure and volume of the gas shown in the table below.

State of gasPressure in kPa\text{kPa}kPaVolume in m3\text{m}^3m3
Before the gas is compressed / at atmospheric pressureP1=101P_1 = 101P1​=101V1=2.04V_1 = 2.04V1​=2.04
Compressed inside the cylinderP2=1717P_2 = 1717P2​=1717V2=0.12V_2 = 0.12V2​=0.12
